this scope is post war made. mostly czech used before and early after the war are the double claw SPORTER version not wartime tall double claws. this was not used 100% of the time almost ANY post war solder on or pressure/friction scope mounts were used as they were sold ALL over the EU. from the little info gathered they made some post WWII military scope that have a c (C) suffix before the serial but i am still figuring this out could be mis-information. I can't find any other scope ppl to talk about it so i am doing this research solo for now since greggdw has fell off the face of the planet with some serious problems good luck to him.
