I called my Pops last night to wish him a happy 74th birthday and while we were on the phone he mentioned a friend of his had recently given him a pistol. Supposedly the friends' deceased wife had been given the pistol by her brother before he passed. He was a cop in Chamblee, GA. Pops told me it was a Smith and Wesson in .25 caliber. I said I wasn't aware of Smith ever having made a .25 auto but he insisted it said Smith and Wesson right on the box. It does, but of course the box is not for this gun. When we got off the phone he texted me these pics. Googling and Gunbrokering seems to indicate it's some kind of WWII era Czech pistol called a "DUO." Values appear to range from $150 to $500. Something about Nazi marks.
Can anyone here tell me anything about this and point me to a real value? Pops isn't a gun guy. Said he might hang onto it, but wants to pay his (very dear) friend a fair price for it since he needs money. Honestly I was wondering if the Smith Box isn't worth a bit based on its condition.
