TV Identification/Breaks My Heart

[LovesZenith]

Today I was driving through my grandmother's neighborhood. I always make it a point to look through every street for anything. It's an older neighborhood, and she was the second person to live on her street (That was 1951), with the rest of the houses coming up around 1953, and I think the last one was built around 1964/1965 (based on what my mother has told me). Simple, two or three bedroom traditional style houses. Back to the point of the thread - I originally saw the set as my family and I were driving to her house on Christmas day, and was unable to get a photo of it. Today, I was able to catch a break in rain showers and caught a picture of it at dusk. (It was sitting in a pile of 10-15 year old silver plastic sets, leading me to believe that someone took advantage of Christmas sales and got all new flat screens, throwing out all of their current sets and mom's old TV that's been in the basement)The ground was too soggy to try to get out and examine it closer. What breaks my heart is that for years I've been scouring the neighborhood for anything, and the time I find something, it's been sitting in record rainfall for a week. The first time I finally have a chance at something, right around the corner from me, the homeowner decided the time to set it out was the day that we got 13" of rain in 17 hours. Ugh, the luck I have.
Onto the set -
I was only able to get one photo of it as I was driving along. On any other occasion, I would have pulled aside and gone over the set, taking pictures. Today, I had to get home before it started to rain again, and before dark. Someone also was coming up behind me, so I couldn't stay to long. My guess is that the set is an RCA from around 1968-1972. The screen was either 17" or 19". It's hard to tell in the picture, but the UHF was a vertical line, with a red bar to tune (Like a radio dial), and the control panel had four big knobs, which I assume would be on/off, volume, UHF and VHF. In the picture you can see a small panel popped open on the front. It had a medium sized knob in the middle, and four tiny ones in each corner. These are almost certainly color controls.
