WWII Japanese Instrument In Case W/Writing

[Otter42]

Would appreciate any help on identifying this piece,  thanks, Ken 

[Mr. Bushido]

I am contacting you in a hurry, but I could not find any wording to identify this item.

The characters are only generic part names, such as "lens".

[Otter42]

Thank you Mr. Bushido, appreciate you looking for me, Ken 

[Otter42]

Put it together,  and tried to get a Pic of the inside lens

[Otter42]

Better pics, and optics are dirty but clear, hard to take a Pic holding the heavy thing with my phone camera. 

[Otter42]

Also just realized is the case it's in is made of brass.

Optics are usually identified by the stenciling on the exterior of the case.

[Otter42]

I'll take some pics of the outside and post later, thanks

[Otter42]

Only marking on the case.

The smaller tag with the numbers 1 9 and 8 translates to: Made in August 1944, Nippon Kogaku K.K.  IF GOOGLE TRANSLATE IS ACCURATE...

No problem Ken,

 

Best,

90% sure it's an armored vehicle fire control sight.  Neat as heck and if it's for sale I'd like a shot at it.  Best regards, Allen

Thanks Allen, appreciate your input.
