identification of prewar FB

Post  Karmannia on Tue Aug 30, 2016 4:18 pm

Hello, I am new on the FB world. I'm looking to buy this FB, I would like to know the model and year. The engine is a Villiers headless cylinder, and an albion gearbox.
Someone can help me to know the year and model?
Thank you!!!

What year

Post  piston 197 on Tue Aug 30, 2016 5:17 pm

Frame and engine No would be a good point, armed with this information I could help ?
Well it is a saddle tank model so is post 1930 ( post September 1929 actually when saddle tank models were introduced, and it appears to have the 12C 147cc engine, and it has slotted wheel adjuster slots rather than a fixed spindle and jockey wheel tensioner

My best guess would be a 147cc Lapwing from 1932 to 1934 , various models in various years, but all lapwings ( Models 25, 25M,28, 33 etc)
But as near as I can get with no numbers, a lot of the frames are the same, so this may not be the original engine anyway ?

engine/frame number

Post  piston 197 on Tue Aug 30, 2016 6:16 pm

The frame number is on the headstock, the number you give is not an engine number, the number is stamped INTO the aluminium of the crankcases and for a 12C will probably start GY or GYF

ngine number

Post  piston 197 on Tue Aug 30, 2016 7:36 pm

X11C refers to 12c engine, 148cc the GYF is the correct serial code for a 12c
GYF engines were produced by Villiers from 1932 right up to 1940
it was fitted in the 1932 Lapwing model 25M,
The 1933 Lapwing 27 and 28
The 1934 Lapwing 33 and 35
After this time the frame type changed and a different tank was fitted to 148cc machines
Look for the frame No numbers with a "B" prefix are 1932, "C" are 1933 and "D" are 1934,
That is as close as I can get without the frame No.
