Buck,
The butt architecture is similar to butt stocks from PA and other areas, but the detail work strongly suggests a New York origin. The cap box engraving looks like New York engraving, as do the barrel bands, heavily engraved breech, octagon-to-round barrel, shorter than normal grip area in the forestock, fowler-type front extension on guard... and particularly the single trigger. When you say you had a PA rifle "identical less the stars" do you mean it had all the other above New York features on it???
