Help with this Erfurt

[pedroMM]

Thank you all for the answers!!
As it has already been stated here this Luger worths only its shooting capabilities... his owner has reached one position in the spanish top 10 historical pistols competition with this Luger so at least it doesn't shoot bad at all...
Just a bad thing..he payed 1.4K for it!!!( Which is what usually happens when you don't care about how you spend your money)

Regarding the date... I can't understand why the date was removed from this pistol during the rebluing works.. Any idea about it?
In hand the gun doesn't look bad.. but it is clearly visible that just the upper part ( chamber, toogle, etc) has been heavy refinished

Just about the aceptance proofs and other marks, could we know more about when could it be made?

Regards
Pedro
