Thinking on this Double Date
 

In my search for a shooter that is just not a collection of mismatched parts I came across this and the seller does not live far away and if it goes unsold, I might pick it up for $1,000. Yes it looks well worn, yet mechanically functional. Does have a "Unit Mark?" of 6.11. below the toggle.

Would be a good one,
I'd bid on it, his starting price is not bad, considering the holster.

The marking on the rear is a provisional Weimar army marking from 1919 to 1922 time.
