I have a couple; the 'far end' of the wish list...
An Astra Falcon in reasonable shape. (Since they were stopped production in the 1970s or so, I've seen exactly ONE, in a museum.)
A Remington model 51 that I can afford.
The next couple I would like, but I doubt I will ever be able to afford:
A Colt commercial Government Model made prior to 1940 (preferable the commercial equivalent to a pre 'A1' version) in factory nickle.
The same pistol in Super .38 caliber.
A Smith & Wesson 1913; the ".35 S&W" caliber auto pistol.
Any one of the custom revolvers built for a now long deceased friend of mine.
A pinned and recessed S&W model 58 revolver.
