Question Identifying a bayonet.?

I bought a bayonet recently, and I wondered of its origin, so I looked it up from identifying marks. On it was a "CSZ" followed by a "V" bellow the 3 letters. From that I learned it was a Czechoslovakian variation, I just cant figure out what the "V" means. Can anyone tell me the meaning of the "V"? Also, on the pommel is "8323'.
