Great post and beautiful detailed photos. As a German living in Switzerland I can relate to this.
When I started buying guns back in 1989, the LGS was a fan of them and had a display of several autos and half a dozen revolvers, including some very fancy engraved ones. The “run of the mill” revolvers and autos were between 4 and 6000 Swiss francs if I recall correctly, and the jewels were 12 to 15’000.

He said he’d never sell those, and they were his retirement fund.

Sadly he passed away prematurely a couple of years ago from cancer, and since no one was found to take over the shop, the whole stock was taken over by another LGS. But some of the Korth are there now on display. Only saw revolvers, but he has another big room not open to the public full of stuff.

I’ll ask him about the autos, and if I can take a few pictures of the revolvers too.

PS

Do I understand you never shot it ? Given its rarity, condition and value I can understand. But if it was me, I’d be too curious not to try a mag or two.
