Hi there: I just bought a pistol that was sold as a Detective Special. I checked the serial number out (178XXX) and it listed 2 possibilities: 1) "1919 Police Positive Special"; or, 2) "1928 Police Positive .38 Caliber (not .38 Special 1-1/4" Cylinder Length)." The gun appears to have been reblued at some point. I don't believe the Seller was aware of all this and I don't believe I was taken ($400 out the door), so I'm not upset. I'd just like to know if you have any ideas what I've actually got here and who might have put it together. I'm rather new at this and I don't know much about either pistol (Police Positive or Detective Special). BTW, the barrel text reads ".38 Detective Special." Any thoughts would be greatly appreciated.
