Mauser 7.65

[RichardO]

Greetings;

 My friend has a Mauser .32cal pistol serial #269595. Left side marking is: WAFFENFABRIK MAUSER A.-C.OBERNDORF A. N. MAUSERS PATENT.
Under the trigger guard, between the grips is engraved Sehupo.Danzig. Then stamped just above this is 666.

I was hoping we might find out when it was manufactored and perhaps some history.

Thank you
