Thanks for the reply. Yes, I got that far with markings. I'm wondering if the style of markings can place it to a particular period in 1945. Late? Mid-year?From your photos the dou45 you pictured was post war produced by the Czechs and sold to Israel. I can just make out the Lion proof on the left side of the receiver. Many dou45 marked guns were leftover receivers used postwar to produce rifles for commercial purposes.
