What Zenith is this?

[Robert Grant]

Going through all the local antique, thrift and junk stores, I happened to come across this interesting Zenith rectangular console.

I've thought for some time that I only had room for one more set, and it could only be a roundie, but this one has a cuteness to it, and it looks to be in pretty good shape.

The set is actually quite compact, but the picture tube measures about 23" diagonal (it would likely have been marketed as a 25" in the day they were allowed to measure tubes by total tube size).

I got the feeling this was "so old it is almost a roundie" from the position of the UHF dial well below the other components, the layout and fonts for the controls, and the provision for an antenna to be connected to "UHF tuner strips" (but no screws, as it has a UHF tuner).

I haven't seen this model in any of the old catalogs I have run across. The label on the rear actually seems to read "17B20", which, of course, is a totally different black and white set (I have one).

Can anyone tell me something about this set from the uploaded pictures?
