Another 1914 HZa WWII Rework

[phatrick88]

Very interesting 1914 Double Date Erfurt rig that I bought from the Grandson of the vet. Notch on the front of the receiver. All small parts are Erfurt proofed but appear to have numbers re-stamped? (see photos). Matching Mauser replacement E/655 barrel. Matching E/63 Mag but has a suffix and + sign. Finish is period original. Holster is a unit marked 1915 Arty reworked Police complete with Erfurt tool.

Would like to hear your opinions on this one. I can't decide if the entire gun was assembled from spare Erfurt parts by Mauser, or if they simple reworked an old gun on hand. How much of this Luger is "original"??
