mine was passing down a family heirloom
This was a rifle I inherited from an step uncle who passed away, but I don't know where he acquired it. He had traveled to Nicaragura frequently, maybe Honduras also. It's a Remington Rolling Block Military about .30 cal maybe smaller? It was time to pass it along to my son who had expressed an interest in it. It's a cool wall hanger, not a safe thing to fire, so I made a rustic looking plaque from circle sawn Pine plank with a few knots. I made the 4 bevels and a block that's a force fit for the trigger guard. The finish, if any, is yet to be determined by the recipient.
