1914 Erfurt Artillery Luger

[tma00]

I have a 1914 Erfurt Artillery Luger. S/N is 4036 as indicated on all appropriate parts except the wood tipped clip (no s/n) and the wood stock (no s/n). I have found no evidence or remanufacturing or modification. Bluing is worn but appears original with little to no pitting. Stamped with "GERMANY" in english. I have not identified all proofs but the ones I have identified indicate military (not commercial). I would appreciate any knowledge anyone can share in determining what I really have and what it may be worth. Attached is a photo. More photos available (please specify viewing angle). Thank you!
