Danzig is not Erfurt

they were made by the state owned rifle factorys Danzig, Erfurt and Amberg for a very short time after the end of WW 1 to find some new work but the allied stoped this. you can compare them with any other german made M 98 hunting rifle.
some collectors have the special taste to find all three of them. the rifles looking very similar only the makers name make them distinguishable.
