James,
Thanks for responding. I would enjoy seeing pictures of your Joseph Griffith rifle, if you wouldn't mind posting a few, perhaps a full length view of the front side and the two normal half-length views of front and back showing full butt out to about 8" past lock plate. Your 48" barrel is longer than Griffith's normal work, and if it has the pointed side facings around the lock plate, it will add to my knowledge of Louisville guns, since I haven't seen that detail on a Griffith rifle before... but I haven't seen one with a 48" barrel either. One reason for thinking the posted gun, while having KY characteristics, is probably more rural than bustling Louisville, is the triggers... a little less polished than the triggers used by better makers in Louisville, and the front "hair" trigger looks like it was made a little farther south to me. But there are always new twists and surprises on these old guns, just waiting to be found out there! I'm a little jealous that you have a Griffith family rifle... does it have a provenance back to about when it was made? Thanks again for responding.
