Judging by the condition of outside of the barrels, I'd be scared to look at the bores. I wouldn't even talk price without seeing the bore condition. The top gun, as everyone is pointing out, is rough, maybe a cut down Fowler that the local porcupine gnawed the stock on?
If you get there and find, as Mr krewson said, that the guns are marked by established builders, or have high quality components, then you negotiate. If the bores are bad, they are project guns requiring a time and money investment.
If it's an option, take someone with you who knows what they're looking at. Don't get too excited at acquiring new toys, we've all been there, and it can go south quickly. An in person inspection may show you 1 or 2 really nice guns, it may show you a pile a parts for someone who likes to reconstruct, but ya gotta look them over closely.
