Something to clarify about Mauser Parabellum.

[Vlim]

Well, it's post 1972 but we cannot give a detailed date without the serial number.
If the gun has the antler Ulm proof mark, a year code either in letters or numbers should be present.
Most likely it's a 1973 pistol.

Value also depends on box, accessories, test target, manual, etc... being present.
