Philco Color Projection System

This was sent to us by Chuck Azzalina. Here are his comments:

I picked up some interesting paper from the estate of a woman, Olga Yeaton, who worked at Philco in the 40's.

They are invention disclosure documents, if someone came up with an idea they documented it with these forms. Olgo was a witness for just about all of the disclosures

I've attached an interesting one here, it is for making a color projection set, possibly based on the 48-2500.
