Hello
I have a plunger 1952 M20/1 frame with a 1953 B31 engine.
I have a M/B centre stand but cannot see where it fits.
Can anyone point out the obvious to me, it did occur to me that maybe it had rear wheel stand originally?
Thanks
Matthew
If it is a ridged frame look for a hole on the frame where the wheel slot is. Also a peg where the spring would attach to.
This is a pic of my M33 centre stand and gearbox plates when I bought the bike. Your plates look to be for the rigid frame with rear stand. HTH
