hey guys so I'm having trouble even finding my antique online... I don't know the model of the shotgun and don't currently have it in my sights.. I'm going to have it appraise so I can have it insured properly due to family heirloom, it is a 1860 Remington 12 gauge shotgun.. Never seen anything like it due to the fact that it uses and hammer to fire it but you load it through a latch.... Anyone happen to have knowledge of said shotgun?
