If you are OK with hammerless, look for a Pietro Bernardelli Europa in 12 gauge. They came in PG or English grip, splinter f/e, oil or poly finish, DT or SST, 3 chambers, 28 barrels with choke tubes, extractors, case colored frame. Not a best gun, but a solid, reliable Brescia SxS, and one of the great bargains of all time. They pop up on the auction sites from time to time.

If you want a hammer gun, look for a Vincenzo Bernardelli Brescia or Italia (more money). Very nice and well made guns. I own a pair of Brescias and love them, but all that I have seen are 2-3/4 chambers and fixed chokes. Mine are English
grip with 30 barrels, M/F, extractors.
