It's a Zenith K731. Pretty common late model radio. I still have yet to refurbish the electronics though. It looks good except for the cane grill on the front which is glued on crooked from the factory and the tuning indicator wants to go crooked when dialing in a station. Here's some pics.

Most of the veneer is good, but there are some chips that would be impossible to fix and it's missing a knob. I have no idea how old it is, but it has two MC and a KC band on it which means nothing to me as I know squat about radios. The MC channels have London, Havana, etc....aircraft, police, military.....
Oh, by the way, nice radios!!!
My parents also have a huge old Crosley that has dials and such as yours, but up top of the cabinet as it's a big floorstander.
