1958 GE Portable 17P1329

I won this set on ebay and it was delivered to me last week, and I'm just now getting around to posting the pictures here. It is a 1958 model portable set that came with the original box. I forgot to take a picture of the box, so I posted the seller's photo with it. All the tubes look like they have 1957 date codes, so I think it was made in '57.

I called the seller and he said it looked like it was barely used. Only some scuffs and paint loss on the outside. He said it was displayed for a while and he thinks the scuffs were just from the handling.

When I got it and opened it up, it looks almost brand new. Very little dust inside, no wear or heat marks, all stickers in place, etc. I was really happy.

It does work, but the picture is short at the bottom. Probably the electrolytics. Since it's untouched inside, I kinda hate to replace stuff. Does anybody think I can put it on a variac and try to reform the caps?










There is a sticker on the CRT that says "Tube Return Registration" and has the model number stamped on it and something written in that I can't make out. Has anybody seen this before or know what it means?
