Polish AK47 (6x2) bayonet with scrubbed year and 11 in oval

[rakysk]

Got this one from eBay, described as Polish, but only one picture in listing.
Well, it is Polish, but it has scrubbed year 1958 and 11 in oval. Serial number is A series and it is not scrubbed.
Was year 1958 and 11 in oval scrubbed, because bayonet was used in different country, not Poland?

Yes exported but for wich country? :/

I have some like that, some are phophated some a rust blued with painted scabbard like yours

Not just factory or military refurb? They wouldn't have cared much about markings

Thanks for replies.
I thought markings were removed because of export to different country, but removal of markings during refurbishment makes sense.

The oval 11 and 1958 are sometimes not very deep stampings, so I can see it getting scrubbed off during a refurb.
