Was wondering if anyone could please help me identify this firearm. It is stamped CE 43 7646 /2 . It also has several Nazi Eagles on it . No “s” lettering by the barrel or rear sight . Is it a .318 or .323 ? Any and all info would be greatly appreciated. Thank you.

Made by J.P.Sauer and Sohn, 1943. Yes, it'll have a .323 groove diameter.

Thank you
