Had to drop the tubes off in the driveway and hop back on the road to pick up this:

but that's for an entirely different kind of forum (although Charles might appreciate). So I spent the rest of the day on the road and now it's dark out so further investigation will have to wait.
The TV has no apparent brand marks, anywhere. Almost all of the caps are labeled Micamold. The tuner has "Edwin I. Guthman and Company, inc", "Chicago Illinois" stamped on it. Other than that, it's a blank. I'll try to get a better look at it tomorrow.
I didn't photo the HV chassis but it's in the Craigslist shot. The HV anode is plain cloth-covered regular chassis wire, which is odd. I imagine we could name it "Sparky" for now, til someone figures out what it is.
