Has anyone ever seen a Browning Superposed 12 ga semi permanently converted to a .410? I have one and dont know any thing about it.Its not a home gunsmith job as the triggers are converted to mechanical not inertia the ejectors are custom and the tubes seem to be pressed and protrude about a half inch.This cost someone quite a bit,to make it a 12 ga again would be better to me but who knows maybey it will grow on me

Never heard of a permanent conversion, although nothing surprises me these days. The switch from inertia triggers to mechanical makes sense for the lighter recoiling .410. Most of those tube brands would knock out with a "tube knocker." Any way to discern what kind of tubes are in the barrels?

this set up may be somewhat removable but Im thinking its pressed in it might be from the early 70s the gun dates at 1956 or 57.I probably will get a plastic hammer and tap it lightly at the muzzle,you would think a well made set like this would have a makers name
