1947 Rca 721 How Many Were Made??

[edison64]

Just wondering how many of the 721's were made?? i got one about 20 years ago from an elderly neighbor, and just last Saturday i got a call from a lady who had a couple old tv sets to give away, just for hauling away. they were up in the attic (back spasams here i come) i went to look thinking probably just 80"s boat anchor unibrand sets. WOW was I wrong, i pulled up to the house, nice older victorian three story, a 60ish lady showed me to the attic she pointed to a blanket, here they are, they were 1 rca 721 and a firestone 7in electrostat set, all look like they were used verry little.
she refused to sell them, just haul em away, we are selling, and need to get rid of thease. i have been in to old tv and radio repair for about 30 years as a hobby and never saw anything like this !!!!!! Now i have 2 of rca sets, i will post pix soon. sorry for the long winded story, but i get excited when i think about it ps. love the forums
