There are none.
You'd be easier off searching auction sites for commercial 1930's zielsechs scopes, they generally in great shape and don't cost arm and a leg.
Military marked ones command a premium and are rare as hens teeth.
There's a few Zielsechs 6x scopes on ebay but I believe the vast majority of those are either commercial or pre-WWII scopes. I bought a Zielsech off there probably 4 or so months ago for a very reasonable price. I'm about to try to get in contact with Vaughn to see if he can complete my LSR build. It came with an original Zielvier 4x but the glass is so foggy it's basically useless plus for a repro build I'd prefer not to use an original glass. It is to be relegated to the collection
