Thanks! My guess is that this unit is from the 1950's. My grandfather worked for several aviation and aerospace companies and got his hands on several goodies. I also have a box of airplane gauges somewhere. I'm curious what those are out of. When I was a little kid, my grandpa gave me a box of misc switches and wire looms. I used to hook them all up in various configurations to lights, speakers, etc. When I got older I think my parents threw all that out unfortunately. Several years ago I was in Hutsville and stopped by the space museum. I looked inside an Apollo luner landing module and flipped out. It was full of the same switches and wire looms that my grandpa gave me. He was one of the engineers on the Apollo project. I wish I still had that stuff. I had no idea.
