Does anyone have historical reference material that could help with reticles? I've found some on gunsights but nothing on reticles. Anyone??

This is the only thing I have on the N-9 Reflector Gun Sight



It goes on to talk about the 100-mile/100 mils

I can scan more pages in if you want.

I hope we're talking about the same thing.

This is from an old Fighter Pilot Gunnery manual from 1943
