One place to ask about vintage Savage O/Us is the Savage Collectors Forum on
www.24hourcampfire.com. May take a while to get answers, but there are several guys there who know their onions on these not-very-fashionable guns.
I've tried
www.savageshooters.com, which has a "Vintage Savage Shotguns" forum, but it seems to be pretty inactive. If you aren't into switch-barrel Savage 110/111/112, etc., there isn't much going on there, IMO. To many guys, Savage=Rifles.
Never owned a 430 or any of its relatives, but I have a friend who has a 16 that he very much likes and has been shooting for at least 40 years.
