I've got three or four 3 inch 16 gauge shells in my collection. At least two are Selby loaded in US Cartridge Company cases and I know one is a Peters. All are really early shells and all came out of California. Never seen or heard of a box but I'm sure they exist as these came out of one. The only spare I ever had went to an LC Smith collector who had a Smith gun with that factory chambering. All the feed store experts at his gun club told him they never made such a thing.
