I just picked this up for $750 and trying to get more information on it. It appears to be a made in 1911 or 1912 but rebuilt later on. Barrel shows 9-44. Curious to see if it’s authentic or something someone may have pieced together. I am trying to figure out if its a good find and also trying to get more input on it and more info with the numbers on stock. I also hear these are not safe to shoot due to the single heat treated receiver, is this correct? Any help is appreciated. Thank you.
