Mentioned this gun a couple of weeks ago. Got it today. It's a 52-2 ser#A237437 ( DOB please). Has the 38 wadcutter bbl and slide. The 9MM slide looks like a 52 slide with the machining marks still on it. Has a 52 front and rear sight. Has barrels marked Bar-Sto 9MM P. Three like this. 5 inch, 5 1/2, and 6, all marked alike and also a like marked 38 super. Bar Sto claimed They didn't make these. Gentleman I got it from said it came from a smith working on the 952 project. He's had this over 20 years and said He got it from this smith at a large trade show or Shot Show. I'll be taking pictures and posting this coming week. Just hope I can get good ones.
