Could that rectangular one be an Emerson, like the one I put up here a few weeks ago. If it is it should have 1 dial each in the upper right and left corner, I can't make out the picture well enough to tell.

I've never seen an episode inside the TV shop, and I've seen alot of them, although probably not all.
Now that I look at it again, I don't think it is the Emerson, I don't see those dials there
