It's been long debated as to whether the 7VT1 picture on the cover of the original TS-18 Motorola service manual actually existed.
Image

The 7VT2 and 7VT5 certainly do and I have example of each. There is also a 7VT3 in brown bakelite but no one could confirm seeing a 7VT1.

Well recently I saw a tip about this odd looking Motorola TV and decided to take a chance.

It just arrived today. Wasn't packed all that well but it survived.
Image

I'm still not exactly sure what it is though.

The label on the bottom is for a VT-71 TS-4 chassis. The chassis inside is a TS-18 and the front mask and knobs match a 7VT5.

Image

So it's either a 7VT1 they made back in 1950 with leftover parts maybe. Or it's a very well done frankenset.

I'll post more in the TV area when I take a closer look inside.

That paint job and decals are trippy and I suspect done somewhat recently.

After careful examination, I'm inclined to say this really is a 7VT1. Here's my reasoning.

1. The curved cutout is done very well

2. The foam CRT gasket seems to be made for this cabinet.

3. The sheet metal pan has no holes for setting the channels. VT71, TS-4 based sets have tuning slugs accessable through holes in the bottom. The tuners in TS-18 chassis are set by stretching or squeezing coils on the wafer switch. No other TS-18 based set has a sheet metal bottom because the cabinets have full bottoms like the bakelite 7VT2.

So they specifically made a sheet metal bottom for this model with no holes and had to add some insulating cardboard to the tuner.

Looks like it's the real thing. I love seeing stuff like this found after 70 years. Electronic archeololgy!

Try this. Lets find out if its oil or latex paint. latex will soften with denatured alchohol. if its latex paint, then we know at least the paint job and decals are recent, even though the decals look old to me. Oil base paint would indicate an older paint job, and if its oil paint, while it may not be an original artistic attempt, at least we know its old.

I'll give it a try soon. Meanwhile, I pulled up this list of Motorola models from a Wallace Teleaide.

Image

As far as I know....

7VT1 = potentially this set ? Interesting they only show it with a TS-18 chassis. Perhaps indicating it wasn't made for long.
7VT2 = black bakelite
7VT2W = ??? ( a white painted bakelite set? never seen or heard of one, but would look pretty cool)
7VT3 = brown bakelite
7VT5B = brown tolex suitcase
7VT5R = red tolex suitcase

9L1 = 8" suitcase
9T1 = 8" bakelite
9VT1 = 8" wood cabinet

I have a Sam's catalog that is about 25 years old, and it shows a 7VT2W on the cover. I've never seen one in real life, but I agree that it looks good (as does the 7VT2).
