I finally own a Zenith roundie and WOW am I impressed with the quality. This set is an unrestored original and still works great. I planned to do a full restoration but it works so well as is I'll work on other projects first. I posted a short clip of the TV playing the color 1957 TV special with Bing and Frank.
