Two Polish bayonets

[michal19]

hello once again!
i'm in possesion of two attached Polish bayonets.Perkun propably wz 24 control marked ''D''in triangle and heksagon(the scabbard marked ''z''in owal.)And Radom Propably wz 28/29 control marked ''4'',''y'' and ''j''in owal. I have a few questions about them.First question is about Perkun's 6 digit number 259124 does it looks for You like an original Polish numbering?or can it be a Soviet number?the second question is about Radom.The barrel ring seems to be removed but on my eye in little different style than the germans done it.Does this modification looks like a typical german reissue?or can it be rather some crude after-war modification?
best regards
