Pretty cool - I've never seen one of these before.

I've got the TeleTone version of this set, it has a small crack in it though.

Someone's selling an empty case for one on eBay that I'd like to have but the price is way too high.

I've looked at the schematics for both version and the TeleTone seems to have been "Muntzed" in comparison to the Sears, it has a really bare bones chassis.

I know the Teletone has only two video IF stages. Using 6AH6s the theoretical gain is perhaps not much less than the average three stage set. I knew somebody who had one that was restored and the picture was nice enough on cable. On an antenna it might not have done so well outside of strong-signal areas.
