Barger, George – unknown – Mark Laudenslager identifies him as working in Limestone Township, but no county is given."
Beerstecher, G.F. – ca. 1860 – Lewisburg – Possibly the same as Frederick Beerstecher
Boyer, George – 1855 – Jackson Township, Snyder Co. He was listed as a gunsmith in 1855 but none of his guns have ever been identified. There have also been suggestions that a Daniel Boyer also worked in Snyder County, but no evidence has yet been found to verify this information.
