For everyone reading this, Poland did make stocks and manufacture replacement parts for the 91/30 sniper. These are known as Polish 91/30 PU snipers.

They are very rare, and can certainly bring much more than 2-3k. Last Gunbroker auction site had one sell for 4600, but I refuse to acknowledge it because it crushes my hopes of ever affording one.

Poland didn't make many. And they all seem to be a bit inconsistent with markings. Some have WZ stamps on the metal, all have at least 1 on the stock. Interesting read.

So yes Polish 91/30 snipers do exist, but Poland never made an m44 sniper.
