Identifying wheelbase type

[jonathanjoy]

Information please
I am in the process of restoring a 29 flyer, how do I know if its a long wheelbase type

log book states reg 31 05 29 UU5518
frame 2857M
engine no. FY 23070
596 cc
Kind regards Jonathan

Hi,
If the M frame number suffix is genuine, then it is not a long wheelbase frame. LWB frames have room between the magneto/magdyno and rear mudguard for a toolbox; ie. the extra length of LWB frames is all in the rear frame tubes, and they do not have the M suffix.

Thanks for that, Brian,
Yes the frame number is genuine as its stamped on the frame, although the engine has changed.
Which models had the long wheel base frame ? , was it just flyers up to 28 that had long wheel base frames ?

Kind regards Jonathan

Yes, Flying Squirrels from late 1926, through 1927, towards the end of 1928, at which point the “M” frames came in for the 1929 “season”. Good luck with your project.

Hi all,

Here’s a spanner to throw in the works. I have two 1927 frames both long type and both with M suffix’s and both are authentic factory stampings in the right place (they did vary where they are stamped). One is ‘Bitsa’ a January ’27 registered FS the other is a frame only and has no known history but is dated as being approximately March ’27 and was a 500cc Flyer.

I have seen other long frame models with M suffix’s. Anything after 1928 will be a short frame.

Maybe the only reliable way is to measure the actual geometry of the frame.

Ps I’ve also noticed a stamp on the inside casting , lower frame rail that runs parallel to to the engine, 4396 A , maybe this could be significant in determining the wheel base length. any ideas ?
