Also to add, there is some info of Zehner rifles over on the German Gun Collectors Association.
I've had some contact in the past as well with the German Gun Collectors Association. Seems some of my now long dead veteran relatives came home from both world wars with some very interesting German guns that eventually found their way to me. Gun geek must be an inherited trait.
Many of my relatives came to the US from Germanic origins in the mid 1800's. Regrettably, they had to go back to Germany 2 or 3 generations later and kill them. I know that was not an easy burden for them to bear, because before they died they told me it wasn't.
Anyway, can't take guns home as spoils of war anymore, they would put you in jail.
But, that's another story...
