If you got it, grab them. Those are in good condtion, check first to see the shells, but that snare is worth it alone. You can't find those anymore in that shape. They are probably later era, but if mismatched, the bass could be a 3 ply, and that is way worth it for the 2 and a floor tom, those each in their own right hard to find, but the snare is the key. Try to talk him down as "unmatched". Maybe with 60 in hand he won't want to let you walk away....?
