I think in Japanese it was called:
九四式対空測遠器眼鏡 (Kyuu Yon-shiki Taikuu Sokuen-ki Gankyou) - Type 94 Suface-to-air Long-range Spectacles
Nice piece mate..if you ever sell it let me know
I also find it interesting to see it in use on a tank! I would of thought tank gun had internal optics etc. Perhaps for longer distances?
not much good in the jungle,what.
I think what Harryamb2 is trying to get at, is that you minimum range of the rangefinder in 100 yards. Difficult to get 100 yards of clear view in dense jungle.
Does anyone have there own examples of this same rangefinders? or any of the accessories, box tripod etc? feel free to post if you do.
What a really neat item , nice find !
We are the Pilgrims , master, we shall go
Always a little further : it may be

Across that angry or that glimmering sea...
