1917 Erfurt

[Mark1]

My first Erfurt , collected yesterday . The seller is a well respected local identity in gun collecting and purchased this one
in the late 1960's from the NZ soldier who acquired it in France in 1918 . So that makes me only the 4th owner !
Came with a JM Eckart 1917 holster , tool and the 2 mags . All numbers are matching except the magazines .
These are certainly different to a DWM , so how did I do ?
The thing is the magazines , I thought all imperial mags were bright metal plated ? The blued mags I have seen are
WW2 with an alloy base . Both mags are full of grease and gunge , appear to me like they have never been apart , so I will
not be stripping or cleaning them at the moment . Would really appreciate some comments from the Forum experts .
