BKA Model 75 "Original" I think it's a Diana???

On the lighter side, I think the Germans we're still bitter about the war at this point. I got the tap for the incredibly fine M10x.75 thead on the sight hold down disc, made the a new disc, bored it and threaded it, only to find out that it was left hand thread.....

Never even thought to look for that. So I need that part if anyone has a spare.

Crank, could you just make another threaded stop pin only with regular thread? They would function but reverse of the original design?? No?...

The pin is threaded then 4 flats are milled on it. Then you have to serrate the bottom. Not worth the time on my equipment. I'll see what I can find.

The BKA is the Bundeskriminalamt or German Federal Criminal Office, similar to our Alphabet org.
Your D75 was likely a training gun, or to shoot rats in the basement of the BKA home office, and then declared surplus?

Glad you reactivated this thread specie....

I would suspect the gun with purchased for the BKA snipers to conduct indoor training. We had 75 T01's at SOTIC in the late 1980's that were used for remedial, after hours training of students that were struggling. We (the instructors) also used them in the winter when we were not teaching just to stay in shape. Most days there was a beer shoot at the end of day. Our desks were on the upper deck of a WWII barracks bldg. It was wide open so we could shoot 10m or so. Everyone fired one shot using the same gun on a standard NRA air rifle target. Farthest one out had to buy a round down the street at the Green Beret Sport Parachute Club on Smoke Bomb Will.

Enough of the stories, can someone please measure the diameter of the barrel under the shroud and the shroud diameter of a 75?
