I found this holster for $20 at SOS.
Some fellow bought the Sauer 38h that was in it(not a Sauer holster) and didn't want the holster.
It is pebble grained and dated faintly 1917, and Hermann (something) over Madgeburg(I think)! Along with a B.A.X. stamp.
Had marks from the Sauer, also looks like it held a 1914 Mauser for a while, and fits my Dreyse too!
