Thanks in advance for help I may get on here. I have recently acquired a Parker 10 Ga Double barrel. the serial number is 36259 with a 2 above this number. I have two sets of barrels for this gun one shorter than the other. both sets of barrels come with the fore grip. Patent number are Apr 11, 1876 Sept 3, 1872 and a third date of Mar 16,1875. The serial numbers appear the same on both sets of barrels. A three and more dates are on the barrels. With all that said can someone tell me what I have. also has Damascus steel on the barrels
