Sold my shotgun and still have the spare barrel available. It's a Remington 1100 410, 'modified choke', with vent rib and a 3" chamber. The barrel is in overall good condition with some very small rust speckling on the top side near the vent rib toward the front. It had this when I bought it 25+ years ago and has never been an issue. I kept it oiled and no problem. I tried to get pics that show it but it is very hard to see. The barrel otherwise is in very good shape and functions fine. Take $165 including shipping for it. I have some more pics if you'd care to see them just shoot me a pm with your email address. BARREL IS SPF!
