HI Blondee
That is nearly identical to the first set we had when I was a kid. A 1953 model. Yours looks like it has 1953 trim with 1954 knobs. Those rounded corners are very recognizable. Take a look at this 1954 brochure:

My dad kept our set running by replacing tubes, and even the picture tube once, until 1965 when we replaced it with a Silvertone color set.
Hope you can save it.
