Which bayonets for my M1 Garand rifles

[Bizio]

Everything there looks good from this distance. No garbage...yes an M6 for sure. Why 2xM5's? Trading material? Or different?

Actually one M5A1 is Milpar Col and the other one is Imperial.
I could also find and reserved an M1 10" with M7 scabbard and one M9.
I think they will be with me in one month hopefully 'cause of the long burocracy in Italy : bayos are considered to be arms and must be registered and need special procedural for ownership transfer.
