This is a Prototype chassis and tube purchased from Harry Poster.
The short of it is this was an RCA Prototype made in the early 50's, one of the Ancestors of every Color TV that followed for the next 50 years.
The ETF is The Early Television Foundation, run by Steve McVoy, their mission is to preserve stuff like this.
