Small Sony black and white tv model?

[zenith2134]

I was given this set a while ago and only recently got to powering it up. It's a 12VDC only set with VHF/UHF. The UHF is on the right side. It is cosmetically rough, but works as new. The antenna is missing so I jammed a dipole rod into the hole where the original went. It gets crystal clear reception from one of my blonder-tongues, but I'm going thru a move currently and my collection is set aside in the interim.
Anyone recognize this set? It's from the early 70s AFAIK.
The sound doesn't work at all and I haven't opened it yet. Using a 12 volt wall wart which originally went with a 802.11g wifi router, it is capable of 2.5Amperes and the set has a ton of emission.
