Part 4
H.P. 54.
H.P. 54 is a 1917 Erfurt, serial# 1357h . It was reworked in the Weimar era, its most immediately obvious change is a DWM replacement center toggle. There are smaller details which will be seen. The barrel is original, demonstrated by the remains of its Erfurt inspection stamp and proof eagle; it does not have a 1920 property stamp on the receiver.
Some of the markings presented here are difficult to see in photographs. I have chosen not to whiten them (except for the H.P. marks) so that detail is not obscured, and because the surface condition of parts of this gun make its application problematic.
