AN EXCELLENT MUSEUM QUALITY SECOND WORLD WAR GERMAN WEHRMACHT ENTFERNUNGSMESSER MOD. 1934 (EM34) COINCIDENCE RANGEFINDER MANUFACTURED BY EMIL BUSCH A-G, OPTISCHE INDUSTRIE, RATHENOW AND EQUIPPED WITH ITS ORIGINAL WaA 1938 MARKED FIELD CARRYING CASE.  This 0.7m Raumbild Entfernungsmesser Mod. 1934* (EM34*) Coincidence rangefinder manufactured by Emil Busch A-G, Optische Industrie, Rathenow was one of the most highly regarded optical rangefinders used by the German Wehrmacht during the Second World War. This is a coincidence type rangefinder that would have been used by mortar crews, machinegun, and artillery units. The EM34 is fitted internally with a series of prisms, beam splitters and mirrors, which divide the viewed image into two halves. When focussed into one image, the range finder provides a calculated distance or altitude to the target. This rangefinder is in superb museum quality condition, with clear and bright optics, near mint paint and finish, high quality leather and metal fittings, eyepiece cover, and very unusually it retains its original padded field carrying case. The leather end caps and the cover case retain some of their original feldgrau and desert tan camo finish, even the adjusting tool is still present.

The EM34 was developed by Carl Zeiss in Jena. Other optic manufactures, like Emil Busch A-G, Optische Industrie, Rathenow, also manufactured the 0.7m coincidence rangefinder. Its predecessor was the EM14 developed during WW1. The original version of the EM34 was developed overtime and the improved variant was designated EM34*. This rangefinder is an example of one of these improved variants. Its a tube like design with large leather pads on each end to protect the objective lenses. The EM34 was usually carried in a padded protective locking wrap but these are now rarely found. Both ends have turnable sleeves with holes, and once turned into the right place, these lenses focus through the holes. They also keep dust and dirt out from entering the lenses. A small adjustable tripod could be attached to the EM34 just behind the main eye piece. Inside the EM34 were lenses and prisms made from a high quality uncoated optic glass. Just inside the right objective shutter to the right is a second shutter with a square window which is locked with a screw. When the screw is turned 90 degrees, the collar can be rotated to two different positions. When the index mark is aligned with the text ‘Berichtigung der Entfernung’, an adjustment drum for the range correction appears in the window. When the index mark is aligned with the text ‘Berichtigung der Höhe’, a similar adjustment drum appears which is used for vertical adjustments of the inverted virtual image as seen in the centrally placed rectangular window when looking through the eye piece. Another small window with the text ‘Entfernungsberichtigung’ around it is used for indication. Inside this window is an index mark with a scale running from 0 to 40, when the rangefinder is correctly adjusted it should read 40. The range adjusting drum is placed half way between the eye piece and the right side. This is used to adjust the range of an object when looking through the eye piece. The distance observed is indicated on a scale when looking through the eye piece.

The optics of the rangefinder are designed to provide 11 x magnification and a 3 degree field of view. The main image comes through the left objective lens. In the middle of the view through the eye piece is a rectangular section on the upper part of the view section. The rectangular block is approximately 28 mils wide and 7 mils high. The image of the rectangle comes from the right objective lens.

The scale is graduated up to 10000m but the best accuracy is at 2000m, once past 3000m the accuracy declines rapidly. The EM34 could be used standing up, kneeling or lying down To calibrate the EM34 you need to follow the steps below: https://germanmilitaryoptics.wordpress.com/chapter-iv-coincidental-rangefinders-the-em-34/

The markings are clearly visible, with the makers plate marked with the Third Reich manufactures code cxn indicating that this rangefinder was produced by Emil Busch A-G, Optische Industrie, Rathenow.  The plate also gives the serial number 68955, the Model EM34* and the magnification Vergr. 11x. The original brown leather field service carrying case, with is marked with the manufacturers details, date and a Waffenampt (Weapon Office swastika & eagle) stamp; GEBR. DRESDEN 1938 WaA 179.  The case retains all of its original securing straps and the small adjusting tool (see pictures).

This Second World War German EM34 Rangefinder is as good as any I have ever seen.  In my opinion they are in much better condition than the exmple held in the collection of the Australian War Memorial as exhibit REL32652.001, which can be viewed online at: http://www.awm.gov.au/collection/REL32652.001/

This 0.7m Raumbild Entfernungsmesser Mod. 1934* (EM34*) Coincidence rangefinder has everything you look for in top quality vintage military optics, provenance, condition and patina; its exceptional.
