Hi. Good picture, indeed. Looks like it could either be some flovor of Ariline, or Silbertone, both which used different companiy gutts because they didn't make their own sets. I have the remains of a 12" table top Airline in a nifty case that is the same Raythion chassis as yours..Rayetheon, back then, tended to make their pictures port hole, like Zenith, but, The Airline I had is Double D like the one you have Diffeerenc is They used the 12" tube on my set, but, masked it down to roughly 6.5"x 10". Beutiful style case, cheap set... Bill
