I have a 1933 bsa w33-6 looking for a piston if anyone got one or even if there is another bike that uses the same piston
Thanks Peter

Is your bike a side valve model.?
I have a +20  piston ,flat top with pockets for the valves
88 mm in height     26mm from top of pin to top of piston   3 grooves for rings
Piston is 85.27 in width
