It arrived today and I am very happy with it its awesome. Here are the mandatory pictures.
It was made in 1954 in Poland as indicated by the receiver stamps.
It seems to have been bedded with burlap, although I am unsure of weather it was to avoid hand guard slippage or help accuracy.
This is the extractor/ejector it is a sled that sits flush with the chamber and when the bolt is retracted a certain amount it throughs the empty case a few inches away. It is quiet interesting.
