Can you help identify this TV (part 1)

[Jeff-20]

I am trying to identify this black and white CRT television. I found the image here, but no other info. Maybe someone can help.

Here's the basic information (pic below): RCA, B&W, somewhere between 15 and 21 inch screen. In conversation it was suggested the model number could be XL-100, but I couldn't verify that anywhere else. It has a unique push button power switch in the upper right corner, three turn knobs under the speaker (contrast, brightness, and volume). Late 70s or early 80s.



If anyone has seen one, is selling one, or knows where I can find more information about it, please post. Thanks for reading!
