Howdy. I picked up an 1894CB45, 10 shot, 24 inch Octagon barrel, recently. I got curios about the date of manufacture. When I went to the marlin site for lookup it did not recognize the serial number ... 98XXXXXX which is on the left side of the receiver rather than the tang (i hope that's the correct terminology) like my other Marlins. The barrel is stamped JM. Any help is appreciated.
