NRA Museums special projects coordinator Ernie Lyles returns to Curator's Corner to show John Popp a rare Civil War-era Triplett and Scott rifle. Meridian Manufacturing made 5,000 for the company. 3,000 were rifles and 2,000 were carbines. It's a seven-shot repeater, using 56-50 ammunition at .52 caliber. The tube running into the stock holds the ammo. Ernie demonstrates how to load the rifle. They were sent to Kentucky to protect General William Tecumseh Sherman's supply lines, but arrived just one month before the end of the war. They weren't fired in anger. As such, they aren't as collectible, but there are still quite a few around.
