Nice 7" Temple TV on eBay

This one looks clean and complete. I don't know why the seller would leave the newspaper stuffed behind the magnifier.

It also seems to have the back which is rarer then the TV. The magnifier just lifts off. Apparently according to the listing the newspaper has been stuffed in there for ten years. I can't tell if the internal mask is there. See first three pictures.

It's just very odd to have such a rare piece and leave that old newspaper on it. Yes, you'd have to ask about the mask. It's probably the least difficult piece to replicate if it was missing, which I doubt it is.

Correct me if I'm wrong, but, upon close inspection, I see a CRT that's bigger than a 7". Even with the magnification it looks obvious that the CRT goes to the borders of the cabinet cut-out. If you look at photo's of this set on the Net, you clearly see where the CRT meets the mask. I don't see that on this one.
I don't know for sure, but I think keeping the old newspaper in front of the CRT might be to make a conversion less obvious. Any potential buyer better ask questions about the chassis and CRT mask. The seller should have pics of the chassis.
