They are a head unit with cassette only no tuner. Looks like they came out of some type of GM Subcompact car.
Model 16062294 and model 16054324

the one on the right is from a mid to late 80's buick skylark. I can't get the pics to enlarge to go further

The radio on the right is the 16054324, cannot find any data on it. From the looks of the wiring assy, seem to have a remote tuner somewhere in the vehicle simliar to a 88-89 reatta. They both look pre delco loc era radios,,,

The radio on the right is from 87+ Buick Skylark as stated and seems to be an AM/FM cassette deck. I could not find any ready information for the other one. Sorry.
