I almost forgot my favorite part: I got a brief engraving lesson, and had my screws and side plate engraved.
The "HAPPY HE THAT ESCAPES ME" was inspired by the same engraving on the muzzle of a blunderbuss in the Baxter blunderbuss book. A similar inscription, "HAPPY IS HE THAT ESCAPES ME" is seen on a blunderbuss in the 2001 Christies catalog of the Keith Neal collection auction. Seems fitting for a 4 bore.
