You could put me down as another potential customer!
My wife and I have just bought a 1927 Ladies Model 201a Royal Enfield in need of tlc.
The mrs has got fed up of sitting on the sidelines whilst I tootle off on old bike runs (her Yam Virago doesn't quite fit in a pre 1930 run).
The 2 speed gear is not of interest (but is definitely 225cc 2 stroke variant), as by '26 a 3 speed conventional gearbox had replaced the 2 chain/2 clutch set up (my 1912 350cc v Enfield/motosacoche has one of those, but subtly different to the 2 stroke version).
Once you've decided what bits are not later model A, drop me a pm, I may be able to help with identification.
Going down to Devon to pick up the Ladies model this weekend.
Cheers Keith
