other) military optics items.    Binoculars, theodolites, periscopic sights, rangefinders, tripods, surveying instruments, etc. -- including some spare parts for German binoculars.  Prices in Euros.


There is one section in English, but don't hesitate to "shop around" the other German language sections to find more stuff of interest.

Subject: Canadian Navy Big Eyes

Another web page with a good photo of "Big Eyes" at work.   Canadian Big Eyes


"May 9, 2002 - Somewhere in the Arabian Sea - On the bridge wing of the destroyer HMCS ALGONQUIN, tactical acoustic

sensor operator Leading Seaman Robb Franklin of Sudbury, Ontario uses the "big eyes" (long-range binoculars) to watch

the British supply ship RFA Fort George sail by. HMCS Algonquin is deployed on Operation APOLLO, Canada's military

contribution to the international campaign against terrorism."

This web page looks like it is planned to index lots of photos of Navy stuff, including "Driectors" which are the large ship mounted rangefinders.     I can only view the stuff using Internet Exploder!



Subject: Web page with stuff on Soviet T-72 tank equipment

Here is a Web page with stuff on Soviet T-72 tank equipment, including SOME stuff on the sights and "biocular" rangefinder.   Just found this, haven't read through it.   Could be lots of stuff here to wade through.

AFV Interiors -- cover shot shows binocular (?) sighthead on Soviet T-72 tank


Commander's binocular periscopic sights -- see pictures 10 and 14  This reminds me of a US tank periscope that was surplused out in the 1960s-70s.


Look at pictures 11 and 12.


Commander's sight -- look at picture 4



Subject: WWII Army rangefinder web sites

  The following web page from the Northwest Historical Association (WWII historical re-enactors and enthusiasts) consists of an article on use of the Vickers machine gun, and includes photos of a Barr and Stroud optical rangefinder, a clinometer,  and a Vickers "dial sight" which looks like half of a binocular on an azimuth dial mounted on a tripod.


"Several special instruments were developed for use with the Vickers. The first was the clinometer, a device that was attached to the tripod. As the barrel was raised it could be measured against the clinometer to find the angle of elevation. In 1939 the clinometer was replaced with the more sophisticated dial sight. A Barr & Stroud rangefinder (which looks quite similar to the model used by German artillerymen) was used to determine the range to targets. If the target was out of the line-of-sight then a map could be used to obtain the range along with either a slide rule or range table for calculating the proper gun elevation. In addition there were charts for determining adjustments du to the relative elevation of the target to the gun and for wind speed
