If the bores scrub up ok, the wall thicknesses are sufficient, the barrels ring; if the locks engage positively and crisply at half and full cock, and the triggers release the hammers cleanly; if the stock is solid and sound, I'd be happy shooting it.
Muzzles can be rod-worn to look paper thin but be fine just inches further down; fences can be quite badly corroded from priming compounds without affecting safety; platinum vent plugs were often peened shut by original owners who wanted more energy behind the charge, not venting out the side.
Look at that action and how thick the corrosion is around the fences and Rockdoc is worried about buggered screws?
Someone took one of the finest shotguns built on this planet and turned it into tomato stake.
One of the finest guns ever built?! I don't think so; good quality gun by a respected maker, but hardly one of the finest. Tomato stake? Pending some actual in-hand examination with appropriate tools by someone who actually knows what they're looking at, maybe a long way from it yet.
