I recently inherited a Mauser-Werke A.G. Oberndorf a.N. Mod. HSc Kal. 7.65 mm. From the research i have conducted (only 2 days!) I can only find examples of pistols that have blued finish. Mine appears to have a nickel finish, with black plastic grips. There are two numbers that appear on the pistol, first is on the forward part magazine well (970446) and the second number is on the bottom of the magazine well (2179). Is there anyone who can help me decipher these numbers and provide me a resource to research the history of this pistol further? Thank You
