Tail Light MT110 BSA WM-20

Hi All,

I have been following this forum for some time and very thankful for the information it contains but this is my first post.

I have just taken ownership of an early 1942 BSA WM-20, I have been told by the second previous owner that Henk has dated this bike as being built around Feb 1942.

Before deciding to buy this bike I was able to track down the previous owners right back to the late 80's where it appears it had been used as a movie "extra".

The bike appears mostly original but it does have a few missing and wrong items if I have read the information on this site correctly?

Over the next couple of months I am hoping to track down the rest of what needs fixing or replacing (I will need to upload photos when I can work out how to do that?).

Firstly can someone tell me if the MT110 tail light is the correct unit for my "contract" model, and also if and where I maybe able to source an original unit as I definately don't want to purchase reproduction items unless absolutely necessary. The closest thing I could find so far is a MT211 light..

All help and information is appreciated.

Thanks Glenn.

Re: Tail Light MT110 BSA WM-20

Hi Glenn. Officially a 1942 bike wouldn't have had a number plate and would have been fitted with an MCT1 fag end lamp. Of course you must have a number plate now and the next best option is the MT110 that you mentioned. Originals a very hard to find and usually expensive and also only have a single filament bulb. You can buy repros for under £20 that come with a twin filament bulb for a brake lamp. The very best repros I have seen are made by Jiri and are virtually impossible to distinguish from an original, but again are not cheap. http://www.vintage-replica.cz/svetlaE.htm

Re: Tail Light MT110 BSA WM-20

Hi Glenn..Welcome to the forum...

I have one of the Czech replica MT110s for my 41 M20 that Ron has provided the details for in his post.

They are a very good copy and at about £65, probably a third of the price of a battered 'original'...

As much of any restored bike isn't 'original' anyway, in my opinion good quality replica parts that are hard, or impossible to tell from the originals should be regarded as an acceptable substitute...

In the case of a machine such as the WB30 I restored that has to be the case as parts are simply unavailable..

This is gradually becoming the case even with some M20 parts as well....Ian

Ian,
Does it have the "Joseph Lucas, MT110, Made in England" stamp?

Re: Tail Light MT110 BSA WM-20

Yes Kostas, they have all the correct text, but probably don't want to advertise that due to copyright etc.

Best repro on the market! was recently visiting a friend who has some Broughs, and he had the terrible cheap repro's on them!!! had to comment on that! why have a 100K bike with a cheapo lamp on it???

Cheers,

Lex

ps, they can still be found original on jumbles etc.

This is the rear of the bike, so what I'm hearing is this is not the correct bracket attached the rear guard for this model?

Re: Tail Light MT110 BSA WM-20

The best you can do is fit a period looking number plate, or maybe better still a pre war BSA style plate. Yours looks ok to me.

I have one of Jiri's in stock and it's all brass with the correct writing on it. You just can't tell it from an original......apart from it's newness. I don't think Joe Lucas is in any position to uphold any copyrights? Ron

Re: Tail Light MT110 BSA WM-20

Here are some more pics, I am thankful for the comments so far and thanks fellas for taking the time to help out. I have checked out the links to CZ. I agree a restro is not original but I guess my goal is to produce a bike that people in the know look at and ask if it's been restored?

At the moment I am still learning about these BSA's and hope I havent jumped the gun too much on buying this one? As I said earlier I can clearly see a couple things but I am sure others will see obvious mistakes. I just hope I havent ended up with something that is totally "out of whack" for the build year... Even before I start.. Or worse yet be searching for bits n pieces that aren't susposed to be on this bike? The more I dig the more confused I am getting.. In comparison my WLA was a piece of cake to research before the build compared to my BSA..

I'm hoping this horn doesn't belong near the other end of the primary either? Seat is cool but I am figuring it's not 100% corect either...

Re: Tail Light MT110 BSA WM-20

Ditch the mirror, the rear light and get a proper battery. Get one of the lights that are indistinguishable from original. Everything else seems perfectly OK to me but there's always the rivet counters on this site to contend with!

Re: Tail Light MT110 BSA WM-20

Well since you ask Glenn and I'm not criticising out of nastiness. I don't like your air and mag levers. Is that a brass carb? Very nice but not correct and the float bowl should be on the other side. Ron

Re: Tail Light MT110 BSA WM-20

An invitation to rivet-count ? They don't come along very often !

If you're intending to restore 'accurately' then you'll first need to decide during which period. Ex-factory or at some point during its service life ? The latter gives considerably more leeway.

Horns changed type and position. Without knowing frame number / original census number, it's difficult to say for certain.

Are you intending to display at shows or simply to have a decent looking bike on the road ? If showing then the best option may be a quickly-detachable number plate, maybe fitted to a pannier, with central WD tail light on a tail section with no extra drillings.

We've discussed the canvas seat covers at length on here. To date, no evidence has turned up to support their use on motorcycles and they appear to have been supplied as gunner's seats in SP guns. Is the Australian 'DD' mark on your canvas original or a later addition ?

You should have pillion equipment on a 1942 bike. Again, types varied over the years.

As Ron indicated, top levers with slotted screws are post-war. I have an idea that brass-bodied 276 carbs were locally made in Australia during the 1950s.

On the subject of Jiri's MT110s, I have an idea that, as per other replicas, they don't incorporate the composite rubber mounting in the bulb holder which was a selling point with the originals. However, any 75-year old original will need unsoldering and re-rubbering by now. The rear part however looks very good and maybe more accurate than some of the post-war MT110s produced by Lucas. Lucas had a serious habit of changing designs without altering part numbers...

The brass body carb was produced by All Parts after the war, I was informed from old shell casings.The carbies work well and Amal parts fit directly. John Parker can help there, if needed.

Hi Glen,

Where abouts in Queensland are you? Jeff Gordon lives at Stanford near Brisbaine. He has a M20 and a WLA, he could give you a few pointers

Re: Tail Light MT110 BSA WM-20

Hi Ron,

I really appreciate your comments and am not offended one bit. I have tracked down what I think are the correct air and mag levers. I kinda figured the chrome jobs were wrong straight off the bat, my guess these are later model ones or they were borrowed and swapped off someone's old Victa lawn mower somewhere down the track...

The only ones I can find so far are a combination of raw steel and brass. Not cheap though at $250AU. I want to search the forum to see a picture first before purchasing them though to be sure.

Re: Tail Light MT110 BSA WM-20

Agreed Keith a another battery or a replica battery case is definitely needed, I seen a black rubber type Lucas case that looked pretty close to original that I would like to install in the near future.

Hi Rik "Rivet count" by all means I appreciate the help, I am used to building WLA bikes and there is reams of information on what goes with what and where. I have found the whole British thing a real pickle of a mine field in some aspects but If I understand it correctly there is little standardisation on the earlier built WD bikes? This units engine/frame number is WM20 54098 and I am led to believe the original 'C' number from the factory was C4635686 (unlike the made up jumble currently on the tank).

As far as I am aware the 'DD'(Dad n Dave) mark is dinky die ridgy didge. I did read in other posts about the canvas seats not being the correct factory fitted item which leads me to the plans for this bike.

If I can't get the dating and correct factory specs and then track down the correct original parts (or very, very authentic reproduction items) for its build contract then I would keep it and re-restore it [so it doesn't look restored] as an in service bike. In this case I seek help to track down its proper war service history.

I am in Australia and would like to know how this particular bike ended up here down south and what if any service this bike saw and what unit it belonged to in the Australian military?

I guess before I shell out on a fair degree of cash on parts I need to find out the above info?

I really like the sprung pillion seats but I have a sneaking suspicion that one of these isn't correct for this bike? and presume the solid guard mount type is the correct item?

Hi Darren thanks for the info, when I get a chance I will take some close ups of the carb and post the pics for all to see.. who knows it could turn up something new that may have not been seen much before and may help someone else. I was thinking of maybe trying to track down a NOS Amal 276 but I have found they appear to come in a few different varieties and don't want to buy the incorrect carb......

Hi Dave I'm in NSW but am hopefully driving up to 'Cane Toad Town' [no offense intended of course] this week to pick up the bike.

Always happy to talk WLA and I seriously need to be brought up to speed on the BSA bikes so am always happy to learn.

I found with the 'Yank' bikes there is so many good factory photos in manuals that you can piece together components fairly easily especially given authors like David Sarafan and Bruce Palmer who make it a total rivet pickers paradise to restore one of these in comparison to the WD bikes... But I guess the real reward is in the hunt not the kill, can't wait to pick up the BSA.

Re: Tail Light MT110 BSA WM-20

Hi Glen,
What a drongo I saw the QLD rego and thought that you lived there. I guess that your NEW bike is there?

Jeff is a forum member, but I don't know how often he visits. Wow, that Bruce Palmer books fetches a few quid.

Henks CD that he sells has a lot of photos of BSA's in service, it also has parts lists for some years. I got mine a few years ago, worth it weight in gold.

I saw your post in wanted. I have the same oil pipes, like Ron says try Russells in London. My friend that lives in Perth W.A.often orders parts for his M20. There parts list is in the links section on the website. Hope that you have a Fax machine? Les doesn't do the Web Still have some original stuff.

I guess that when you get the bike, you will be able to see what you need. Keep us all posted.

Dave
