If it is Tokyo Optical company, then this was I think connected to Topcon.

Hey Troub. Tokyo/Topcon has been confirmed via an old Peter Abrahams file.

Hey Binastro,
Uncoated optics and a magnificent wide view: they're 10x 7.1° for sure. I'll post more photos...wasn't sure this thread was suitable here. BTW: prism cover screws match, it was the camera angle.
From CN forum what I'm learning so far:
- The marking in quotes beneath No. 214 could mean Scale in Lens or Greater Japanese Empire
- The marking on the left prism plate stands for Naval Aviation
The circular marking on the right prism plate has not yet been identified
One mystery remains: the meaning of the mark in the circle.
New information gleaned from a parallel post on a popular astronomy binocular forum. They were designated as Naval Aviation binoculars and were property of the navigation officer aboard IJN Submarine I-36.
