Just for info, the gun used to kill Franz Ferdnand was not a .32, it was a Browning Model 1910 in 9mm Kurz (.380ACP). Four guns of that model were provided by the Serbs; the serial numbers were 19074, 19075, 19120 and 19126. They were in a Vienna museum until stolen by the Russians during their occupation of Austria. No record was kept of which one actually was used to kill the crown prince.
There is a question about the number of "Baby" Lugers made. At one time, August Weiss said there were four, two in 9mmK and two in 7.65mm (.32ACP). One, in 9mmK has turned up, but I don't know who has it now. There are or were repros being made for $20k or so, if memory serves.
The pistol supposedly used by Adolf to do himself in is a 7.65mm Walther PP, highly engraved and heavily gold plated. (It has been described as "solid gold", but Walther employees who have supposedly authenticated it called that nonsense, saying that a solid gold pistol would not be functional and that Walther would not have presented a phoney gun to the nation's "leader".)
It sold several years ago and reportedly is or was owned by a Canadian collector. IIRC, the sale price was over a million USD.
