Hi,
I am working on an ad for Motorola and am looking to buy or rent a 1957 motorola metal, portable tv for the ad. I would be interested in other models that are portable and from the 50's as well but am only interested in motorola products. If you
have any or any sources, I need to find these items asap. Please Call
917-690-7635

Funny enough, we were talking about '57 Motorola offerings not long ago. See this link:

Might not exactly be portable, but for a rental I'd get in touch with the owner....it's the only 1957 Motorola color I've ever seen.
