Aushilfsrichtmittel 38: Auxiliary Quadrant Sight 38

Aushilfsrichtmittel 38: Auxiliary Quadrant Sight 38This quadrant sight is called a “substitute aiming device” by the Germans. It will fit into the sight mount found on the 7.62 cm Pak 36 (r), the 5 cm Pak 38, and the 7.5 cm Pak 40. The device has apparently been designed as a cheap instrument for indirect laying and may be used with any weapon having a suitable adapter.

The elevating worm wheel housing fits into the adapter bracket and is retained by the elevation worm wheel. The telescope bracket, which is made of cast aluminum, is fastened to the elevation worm wheel by holding screws. The cross-level vial and longitudinal level vial are part of the telescope bracket assembly.

The cross leveling mechanism consists of a worm meshed with a worm wheel segment cut on the adapter bracket. Turning the cross leveling knob causes the telescope bracket and elevation worm wheel assembly to be tilted in relation to the adapter bracket. The azimuth mechanism consists of a worm and worm wheel provided with a rather unique anti-backlash arrangement.

Both the elevation and azimuth scales are divided into increments of 100 mils, and each is supplemented with a micrometer for 1 mil settings. The elevation scale is graduated from 0 to 1300 mils. There is a simple elbow telescope with a reticle design consisting of a large inverted “V” and two vertical lines such as is found in the German panoramic telescopes.
