Here are four I built. The top is a Green River Leman. I took a rifle building course at the Green River Rifle Works in 1978 and the instructor drilled the ram rod hole out the bottom of the stock. I designed and fitted this one.
The second one is a Christopher Hawken Lancaster I copied from photos. The stock developed a crack and I designed and fitted this one to the finished rifle.
The third one is my copy of a Jacob Wigle rifle (Westmoreland Co. PA). This rifle was found in a cave with a mixed blood child "mummy" in the 1920's. I cleaned the rifle up for a museum and have made exact copies of it since. This wear plate is lozenge shaped and was deliberately built a little lop sided. Western PA rifles frequently were built with wear plates.
The bottom one is my copy of a Thomas Oldham (Bedford Co. PA) rifle. It is as exact as I could determine from photos in books. Bedfords also frequently were built with wear plates.
