Topic: Help identify a scope.

I received this scope, along with other items, from my late Grandfather who served in WWII. It has 3x magnification, crosshairs that can be illuminated for night action, and is of a very compact design. I have been thinking it was an odd shape for a rifle scope, and figured it maybe came from a tank, as my Grandfather said he was a commander of Sherman tanks. I have been looking around on the net, and have found similar descriptions that make me think it's from a tank periscope. Does anybody have any info they could offer?
