BSA W32-6 ENGINE

[bsareds]

Hello, my name is Angelo and i'm writing from Italy.
 
I need to buy a cylinder and head for my BSA W32-6 (side valves) and I would like to know if someone have them.
 
I've seen a lot of photos on the web and from the analysis of them I  suppose that the cylinder of W32-6 is equal to the cylinder of W 33-6, W 34-7.

Waiting for your help.
Angelo
