I Have No Idea
I told my husband that he should bring me home some parts from work if he was just going to get rid of thm. I expected some little springs or dead circuit boards. This is what I got. They are some kind of gauges from an airplane cockpit. They were something that was going to get scrapped. I am at a loss as to what to do with them. The faces may be cool incorporated into something, but what?
They do look cool when the housing is off them
