"Eh I don't think so. I cleaned it up a little bit and found a Us Army stamp around the inside of the bezel. "
So...Maybe an Army Tire balancer. Does it have fluid in the center with a bubble? It might not be but it looks like a field balancer.

Nope. I think it's some sort of sight.

Are there 2 sport mirrors or just the one? Remember I was the first to ask

Two. One in the trunk and the other still on the car. Why?

I did a little searching and it may be the leveling assembly of an old bomb sight used in WWII (Army Air Corps).

I was wondering that. It does have lenses on both sides. I sent a message to the PO, we'll see if he can tell me
