The sight head contains the computer which calculates the point in space where the bombs will be released.Below the rubber eyepiece is the optics cradle which the bombardier sights through.This very sight was used recently to actually drop bombs for a reenactment for a television series called Warplanes. This sight was installed in John Ward's North American B-25 Old Glory and we dropped 100 pound practice bombs at a WWII Army Air Force training base.
The B-7 mount is the typical mount used in all of the mid to late war Army aircraft like the B-17G, B-24, B-25, A-26 and the B-29. The Bomb Sight Head mounts to the stainless steel gear and brass bushing on the upper right end of the stabilizer.
The sight head will pivot about the yaw axis on the Stabilizer.
The Bombardier controls the aircraft through the autopilot and will direct the aircraft on the bomb run.
The connection to the C-1 autopilot is made through the Directional Panel which mounts on the left side of the Stabilizer as shown in the diagram below.
The Army seems to have used a standardized mount in its aircraft.
The early war mount was usually some form of the B-6 mount, which was later replaced by the B-7.I am also looking for any bombsights parts, components, accessories and technical information for the Norden, Sperry or any other bombsight.If you have anything that might be of interest please let me know by e-mailing me at [email protected] fact this is the probably the most famous Norden Bomb Sight of them all.Victor 4120, an M9B, is the sight that was used by Tom Ferebee to drop the first atomic bomb on Hiroshima on August 6th, 1945.This sight is presently installed in the nose of the most famous B-29; the Enola Gay, which resides in the National Air and Space Museum at Dulles Airport in Washington DC.This is an M-9B bombsight head (L-9772) manufactured by Lucas Harold Incorporated.
