Does anyone have a photo showing the bottom fixing on a blackout mask? My main headlight unit looks to have had a threded lug brazed on the bottom and if I decided to change to a mask, wondered what the fit would be? Ta.

Lee, the fixing on a DU42 lamp is the same as used for the ordinary rim. Ron

Thanks for that Ron. Mine has undergone surgery at some point and looks nothing like the original. Are those clips still available?

Hi Lee, Have you got a DU42 6" headlamp or a DU142 8" headlamp?..Some of the 8" ones had different rim fixings...Ian

I think I can vouch that Lee's M20 has a 6" headlamp, having ridden it once
This is the DU142 8" headlamp screw fixing that Ian is referring too. Later DU142's had that same spring clip but I don't know when the change happened. Ron

Peter was selling some of those clips for the 8" NOS.

These pics show the brazed bottom fixing and a repro mask that I'd like to be able to fit/remove when needed.
I'm not sure if the brazed fixing is an original that's been patched or a later addition, but I'm hoping these pics will help.

Thanks for all the help.

Lee that repro mask of yours is made for the post war MU42 lamp, which has a kind of sprung loaded hook fixing........Why would anyone make such a thing??

Doesn't the hole in the bottom take the pressed in 'tit' in the flat rim clip?...My original mask that I have just sold had it and also the NOS DU42 rim that I have bought to replace it...Ian

You could be right about that Ian. I was forgetting about the little pip on the clip. It's just that I can't see the little step that is normally on the bottom edge of the rim. It will probable still work ok though. Ian and I have both had issues with getting rims to fit shells. Quite often you will have to adjust the locating flange on the shell with a pair of pliers. Another tip, is to slacken the shell locating bolts before fitting the rim/mask, as these can distort the shell when tight.

Good luck. Ron

I always have problems with the fit of the rims..even when I have had a NOS rim and shell. I have recently had to do a load of 'tweaking' to get a NOS rim to fit a very good used shell in readiness for the rebuild of my M20. I always do these off the bike prior to painting (I've learnt the hard way about that) but it is a good point Ron makes about shell distortion...Even a rim which is made to fit well off the bike could become problematical if the shell is pulled out of shape after fitting... ...Ian

My bottom fixing is a very special one. I guess homemade.
It is a split (splitted?) Rim. Only the clip looks standard.
Ever seen?
