What's it worth? Did I over pay?

Picked up a 1951 RCA 6-T-71for $30. Don't know much about it. Picture tube isn't busted, and it's there, so that's a plus. Picture tube was put in on Haloween of 1961 so I'm assuming that there is a decent chance it could be good still. Dusty. Cabinet is in great shape. Only the occasional nick here and there. Did I get a deal? He wanted $50 for it, but that was much to high in my opinion, so I haggled him down to $30. What's a set like this worth? I'm just starting a RCA T-120 restoration, so I won't be digging in to it anytime soon . . . Just thought I'd share my catch.
