Jim,
Below is what I have on the gunsmith John Edmonds that worked in Centre County, PA. I believe he may have come to Centre County from Northampton County, PA sometime between 1850 and 1860. I don't know enough about Northampton gun architechure to know if your rifle possess features that would be commonly seen on guns from that area. To me it does not look Upper Susquehanna. Perhaps your rifle was made before John Edmonds set up shop in Centre County. Nice rifle. Thanks for posting the photos.

John Edmonds worked as a gunsmith in Aaronsburg, Haines Township, Centre County circa 1861. Before coming to Centre County he worked in Bushkill Center, Northampton County, Pennsylvania. His father may have been John August Edmonds, a schlossfeiler (lock filer) in Plainfield and Bushkill Townships in Northampton County ca. 1792-1825.
