The Poles did produce their own Mauser variant, and their own M44 Mosin Carbine variant.  Both very good quality examples of their respective systems - but very different rifles!  He simply didn't know his own rifle.
I once bought a Steyr Stutzen Rifle(Carbine length but with Rifle sights and hardware), the M95M variant that was rebarreled in 8X57 caliber because the Yugos did not want ammo logistics problems.  Kicked like a mule!  But the pawnshop had it tagged "Mauser Rifle"........  good for me, as the price was far lower than the proper M95M should have been.
