So I stumbled across this Early scope (If you call it a scope) in an antique store, any information on it? I've seen bare bones minimum from my searches, namely a few photos and limited info.
It's kinda cool though, not really much practical use, but it would be cool to see it working again.
No labels on any of the knobs either, I figure a manual must be in existence somewhere.
