This one isn't a rifle but a 28 bore shotgun. The plan is a rising bite, sidelock, bar-in-wood with a straight grip, splinter forend and percussion-era grip safety and wedge forend retainer.

The barrels, raw tube is on the left and rough filed tube is on the right.

Lump and rib extension blanked

Clamped for silver brazing

The frame, so far
