HI Aaron,
Thank for the interest in this topic.
Usually the Mauser Parabellum imported by Interarms are not dated. Your pistol should have the internal Mauser FBM mark. Actually it is possible to find Interarms pistol with the German marks (Ulm mark and related date).
In the Interarms pistol, sometimes the date is written on the test target.
Hugh thank you too for the information.
Is your pistol dated?
All information about serial number and date of production is really appreciated.
Thank you guys.
Ciao
Mauro
