Best wishes to all the forum members
I am here for the first time
I would like to ask what should be the number on the fuel tank - BSA WM2079060 ?

This bike was delivered under a slightly difficult contract numbered C13290. 10,000 machines, WM20 71818 - WM20 81817 with 5000 to Royal Army Ordnance Corps and 5000 to Royal Army Service Corps. There were two blocks of numbers, C4752401 - 4757400 and C4860801 - 4865800. Unfortunately, it's not clear how the numbers were allocated to each destination. Was one block finished before the other ?

If they were built in consecutive order, then WM20 79060 was probably C4863043.

thank you very much for your help....will be painting the tank soon....

This image shows C4863137, so less than 100 away from yours. You can see that BSAs from this contract had the number in one row, unlike the Norton behind which has the 'C' above.

We know from the Key Cards that the C4752401 - 4757400 block was completely delivered before they started making the C4860801 - 4865800 block. So I can confirm that WM20.79060 had census number C4863043.

Hi Grzegorz,

Number WM20.5874 is a contract C/5110 bike. Theoretically the census number would have been C3929292, but from the Key Cards we know that there were a few anomalies with the census numbers from this contract and in reality your bike had number C3929293. It was despatched from the factory on September 28th 1939. Please note that the census number "style" (C on top of the number) differs from your later bike (C in front of the number)...

As can be seen in the pictures below ("sister" bikes of WM20.5874), a lot of the C/5110 motorcycles were sent to France with the BEF. Makes you wonder what the story of your bike may have been: BEF bike captured by the Germans and sent to the eastern Front, and then back to Poland...?

I bought the motorcycle in Sweden....so there is its histoia...I just don't know why the documents show 1938 year of production?

Darryl is your motorcycle like the original?I'm curious because I'm doing a restoration of mine right now and would like it to be very close to the original....

Sadly not, was an older restoration but in very bad shape. Bad paintjob, wrong wheels, B33 engine etc. I am now doing a full restoration now.
