Help to identify my wheels

[Michael44]

Hi everyone!
I'm new to this full room and New to Kawasaki zxr400 I recently purchased a race bike and currently recommissioning. The previous owner supplied various parts and spare wheels and I noticed on the rear rims summer stamped with j one stamped with a b and one that looks like a v can anyone explain the difference as a spare rear wheel seems to take a smaller cush drive

Got any photos? Can only see A and B in the microfiches, although some may be marked CJ or DH ?

Okay thank you. I'm trying to attach photos but the photo is saying it's too large to upload

What is the size of the file? I will check the board settings.
