As already mentioned the piece with 1484 is wrong because there was used the czechoslovak number, the fakers didnt understand what is there stamped on pommel, thats the reason why they used this serial, same as You dont know what for mean have this number.In 1939 there were not any reworks of Vz.24 rifles. Same as Your dates stamps are always different, is no other pcs of equipment that would be so overdated as this.The piece was reblued as part of reworking, so it was done later not in 1939.
