Hazeltine is/was located in Mass if I remember
correctly. They made a lot
of RADAR consoles, we used them in the USAF. I do remember that the ones we
had used electro-static deflection. You could rub the screen with a nylon
cloth and the image would smear all over the place.
I do not think that is the same Hazeltine, but I could be wrong. They were
a pretty big contractor during World War 2, involved with radio and IFF
equipment.
