Old military periscope

My grandfather recently passed and left me, among other things, an old handheld periscope of some sort. I've tried researching this and find this does not seem to be a trench periscope. I can't figure out what this is. I put a few photos of this item on an online album at http://picasaweb.google.com/silverwing82/Periscope

I'd greatly appreciate any insight that you might have on exactly what this is??

Thanks,

Roy

I have seen many periscopes but never one exactly like this one. It could be worth a fortune to a collector.

I found something similar, but of apparently Japanese manufacture.

I searched "binocular periscope."

Well, it's also not like any U.S. tank periscope I've ever see, either.

That's closer than anything I have seen so far.

Thanks for the lead. The binocular periscope at the link you sent is sure closer than anything else I've found.

It is a field telescope similar to the type in this picture:

These were developed from trench telescopes. They make it possible to look over an obstacle without exposing your head. In addition they make you taller and thus increase your field of vision. Since they are heavier and more ungainly than binoculars, they were mostly carried by motorised troops such as armoured and artillery units. The larger types were mounted on tripods.

Does that guy on the left have a machine gun? Or is he just pleased to see me?

I have wondered why the legs of the periscope are spread when in use (I know I am inviting another shot at the goal by his lordship Very Happy

), but I think it is to increase depth or judging distance. Range finders for artillery had lenses that were very far apart.

It must be a female periscope.

@HIMQHN,

You have a range finder. Look at a target focus into one clear image record the settings u will have the correct range to target

@HIMQHN,

Your optics are a range finding device
Used to obtain range to target for artillery or any other reason distance needs to ne known. When objects are focused into one clear image u have the range
