Man, that's a beautiful collection.
A friend of mine had two prized items in his at one time extensive collection, I believe they were a Luger P08 and a "Broomhandle" Mauser (C96? I'm not too up on antique firearms but I remember his descriptions of them).
When they changed the UK Firearms law in 1996 to ban all pistols from private ownership, he had to hand them - and all the other pistols, including his cherished 1911 - in to the police to be destroyed. They wouldn't even pay compensation.
He said it was one of the saddest things he's ever had to do. Looking at some of yours, I can understand why.
Very sad, but it's nice to know some corners of the world allow such collector's items to survive. Thanks for showing us these.
