Hi Lukas and other guys involved with m22 / m23 BSA projects.
Mine is M22 two port model with engine JM22 and frame JM19 prefix witch is correct for 1938. Yes, they rare and during the restoration process you have to use us much your brain and technical intuition, workshop step by step accuracy, old catalogs (hipolite, lucas, amal ect) as well with old photos to did your job correct.
I’m lucky my m22 is again on the road during braking period, ca 1600 km without serious issues, one non standard improvement with 6V DC regulator – WASSEL, and some inaccuracy against factory spec with exhaust mounts and leather seat in bronze color.
Lukas be careful with engine parts e.g.cams, lifters, piston, and 2 port cylinder head, they are very unique for the model and rare on the market.
For parts i can share pdf catalog, please grab it:
