Luger Erfurt 1916

[Welsh72]

Folks new to the forum. I have always thought Lugers were cool and wanted one. Actually I surprised I have waited this long to get one. I have been offered one...pictures below. Bore is about 7/10. It is unit marked. Grips are not match but left one doesn't have the chip from the safety lever that most have. The firing pin is not numbered. Believe armorers replacement. I believe original finish. Small discreet export stamp Germany on frame. So maybe imported in 50s /60s. What would be a fair price for this and a good price? Range? I have looked on Gunbroker but they are all over the board....depending on finish etc etc. Want to be fair but don't want to pay 2 to 3 bennies more than I need to.
