Thanks for the comments everyone! Steve, thanks for giving me the makers first name, which led me to discover the following information about the builder.
In Kauffman's The Pennsylvania-Kentucky Rifle I discovered,
Samuel Forker was born in Brownsville PA on 25 November, 1798. He settled in Meadville PA in 1828 where he built firearms. He was a county commissioner in his later years and died in 1860. He was granted a patent for an "improvement in firearms," relating to a design in which four loads could be discharged in rapid succession from a single piece.
He was the father of W.H. Forker, who also maintained the gun maker trade.
With the above information, and looking at the piece....would anyone dare to take a stab at the approximate dating of the rifle? This is my first original, and I'm quite excited!
