Old Black & White Zenith TV

[Cinderbug]

I am cleaning out a house and have found a very old black and white Zenith Television - I would venture to guess 1950's. It has a gold colored metal case all the way around and two knobs on the bottom..one on the left, one on the right. There is a speaker at the top of the TV towards the back. There are also rabbit ears to go with it. I do not know much more than this. I am assuming it works but do not know. I have included photos. Could someone tell me how to figure out the value? Thank you so much.
