Japanese Optics

[hchris]

I was thinking the other day, does anybody know what type of optics the Japanese Army used during WW2 for tanks, guns and sniper rifles etc?

Where could I find information about this toic? What did the reticles look like?

Here are optics for small arms, if you wanna know info on any of them I'd be willing to translate some of it. Google translate ought to say which ones are for what.
