What do I have? What is it worth? 1960's Zenith & GE Televisions...

[throwbackent]

I work for a window company and on a job today a young couple just moved into a house and were throwing all of its contents away. I ended up taking a few TVs off their hands for free. I have no idea what I have or what they are worth. I do know that they are both in great shape. The GE television turns on with no problem, but as far as I can tell, the Zenith one will not turn on. I can't get it to power on.

The first one is what I believe from my research is a 1960 General Electric Television. It's model number is M604VBN

The second one is a Zenith Service Saver Chassis. I decoded the model number and I believe it is a 1967. It's model number is X23174 and the other number, which I believe is the Chassis number is 14N22.
