I have a question about the rangefinder in use. As an old gunnery officer, we had a similar device as a backup to the radar control system. It relied on a stereoscopic system in which you had to superimpose the two images on top of each other to determine the range. This could not be done in the German system as shown unless the two arms folded down as there's not enough distance separating the two lenses. Does anyone know if this is the case?

Al,

I have to agree about the positioning of the arms of the rangefinder. I have also been a forward observer for field artillery and a photogrammetrist so spending my days observing stereoscopic imagery to draw maps, and know that to use this piece of equipment you need a wider spread for the lenses.

Maybe he's only just emerged from the hatch, and is setting up ????

Or maybe the sculpter had never been a forward observer and just had a picture of the device without knowing how it worked . . . {sm4}

Pictured above is just the scissors periscope. They absolutely could be used as depicted. The range finder was the long tubular looking thin that was a couple feet wide. Ill dig up a picture later.

Wayne,

you beat me by 20 minutes .... it is not a rangefinder.

I also have been checking on that and YES, it is a Scherenfernrohr (scissors telescope)

More information here ....http://www.panzeraufgd.co.uk/optics.html

This hybrid between binoculars and a periscope enabled the observer to remain safely concealed in dug outs, behind walls or even tree trunks with only the objective lens visible to the enemy. 1905 saw the design refined further with an army-issue variant and a field artillery model being trialed and adopted. Naturally other countries produced their own versions of the scissors telescope and when World War I broke out both opposing armies all along the Western Front observed each other from their trenches using such equipment. By World War II the design remained virtually unchanged except for an upgrade in magnification to 10 x 50 and continued to be a useful tool in the Wehrmacht for general observation (in both vehicles and on the ground) and for artillery fire observation and direction throughout the war.

Looks like that guy didn't read the instructions, he's not concealed at all {sm4}
