Are these TV's Roundie's Rare?

The set is back home, and I took some pictures to post while I have it. It was in a very upper end part of town with large mansions all around. The house was built in 1951, so the custom built in Dumont was original to the house. The Sentinel looks like it was purchased by them in 1956, placed in the game room, and never moved. It still has many original Sentinel tubes with 43rd week 1955 and 13th week 1956 date codes. The crt is the original 21AXP22 with a date code of 17th week 1956. I was surprised when one of the workers for the sales company told me they plugged it in and the set worked with a good picture. Sure enough they had a set of rabbit ears from a modern portable set sitting on top.
