I don't have access to my manuals at the moment but I will take a guess here.
#1 is from a car, probably early fourties.
#2 looks similar to a 54 Chev truck or car radio.
#3 looks similar to a 55 truck radiio.
Somewhere there should be some numbers on them. Often, just inside the back cover there is a sticker with the model number. We have a list of radios descriptions by model number, in the tech tips.
