Nice that you received an original scope.I got one today. 1942 Ishevek, wartime stock, all stamped matching, scope dated 1942 with a refurb square and dated 1959. I am very impressed...it has an aluminum base and mount. I have to start research as to how long it will take to stress and break, or can I put a steel one on in the same holes. Who knows, gotta get started!
