GUN SIGHT

This is just a place keeper.  I need to make the base a tube instead of a cylinder and then add a projection lens in the center.  It also needs a mounting bracket for the "hud" plate. These things worked just like a "modern" red-dot pistol sight.  The projected ring, cross-hair and dot seen by the pilot did not move on the target as the head moves (within limits) taking the pilot's head position out of the sighting equation to a large extent.  The projected diameter of the image was adjustable (I believe) so that when the enemy aircraft wing span was near the image diameter it was time to "mash the pickle" under the left thumb and walk the tracers onto the target.  The sight image would not be easily visible from outside the cockpit.  The disc was optically arranged to reflect the image from the upward-facing projector optics horizontally at the pilot.  All of this detail could go on forever.  There has to be a stopping point.  Some of the sighting surfaces were round.  Some square.  A square mounting bracket would be easier so the surface might get changed to square just to make it easier.

Blogger is also driving me nuts.  Why is the image different when posted than when set up in the dashboard?  How can the default font get changed?  What happens and what instructions say should happen do not appear to exist in a mutual universe.
