Kirk;
  The first thing that I noticed is that the paint on the back of the safety glass appears to be lifting in several places, the shadow mask also looks a bit spotty, I would want to have a good look at the TV chassis because of this. If you knew for a fact that the picture tube was good I would say maybe $125 at most for it, of course you won't know if the flyback or the other stuff is still good. Early Philco TV sets have issues with the high voltage dropping after the set has been playing for a while, apparently it's an issue with the early Philco Phlybacks. Untested I would say up to $100, just like with radios the big combo units tend to be less collectable then the stand alone TV sets, with smaller table sets being the most popular. Bob Andersen would be the best one to ask about this.
Regards
Arran
