Hi I was redirected to this forum in hopes of finding value on my U.S. revolver Co 22LR marked 149. It has plastic / rubber grips , it is a 7 shot , top break , 149 under the trigger guard, and 149 under the left grip. Approx 80% of plating remains, gun Barrel is a bit loose , trigger guard and hammer are bluing. It is marked U.S. revolver co on top of the barrel. No other markings observed. I am hoping that this is one of the early first models as it has such a low serial. From reading previous posts I understand this is the cheaper mail order version of the Iverson?
