And gives it the gunsight it was originally shipped with. Both osti and wribel. Then the player would need a key press equivalent to the target's speed knob to move the primary ring in and out from your eyepiece. That was the biggest weakness with this aiming system. Gunners ended up eyeballing it using the tracers because someone had to guess the speed of the target before moving the ring.
Schwebekreisvisier 30/38
But I guess as a game play concession Hitech gave us the less commonly used Flakvisier 35.
For direct fire that little telescope mounted next to the Schwebekreisvisier had this reticle pattern.
As for the Flakviseir 35 which Hitech mounted to the osti and Wirbel. Here is why I added range marks to the AH3 reticle: Analog correction controlled reticle.
The Visier 35 is a projection type sight. It uses a light bulb to illuminate an image onto the sights glass image plate. When you look into the visor you see a illuminated sighting image. The gun sights accuracy is controlled by the Correction Box located on the port side of the gun. Sight & Correction Box are connected by a horizontal tube running starboard to port, linkages & connecting rods are connected to the elevation linkages controlling azimuth.
