I have recently purchased a detonics from a private party who knew nothing about it.The gun is a stainless 45 acp, and has a black wraparound grip (Pachmyr) There are no markings other than the name and place of manufacture,"seattle wash.", and the serial no. c21397. I am wondering what model it is, and it's aprox. value. The overall condition I would rate as "good". Mechanical funtion, also "good", although,it does not seem to like aluminum(blazer ammo) cases(jams), ).Anything you can tell me will be appreciated
