The changes occurred in late 1963. Any 1964 or later Model 94 is "post-'64". The changes included internal and external changes to make the firearm easier to manufacture. Some of the changes are: stamped (later cast) cartridge carriers, different receiver design to allow for fewer machining steps, use of screws for link pivots, coil spring instead of leaf mainspring, changes to bolt to make it easier to machine. There is not a lot about the post-64 guns that is "bad", they are just different from the pre-64 guns (and way different from the pre-WW2 guns).
