Possibly an engineering sample of a short necked Predicta Tube?
Did Philco engineer their own tubes at that time or did they sub contract that type of work?

Philco OEM CRTs were manufactured in Lansdale and sent to Philadelphia TV assembly in specially built freight cars with internal conveyors. When the freight car arrived at the TV plant, the conveyor was connected directly to the assembly plant conveyor where they were picked and installed in the TVs. By that time TV assembly had consolidated on to the first floor. Engineering was done in Lansdale and Philadelphia. R & D was done internally as well as outside. Manufacturing Engineering figured out how to make a lot of stuff fast, inexpensively and get it shipped.
