WWII USAF Bombardier's Bomb Release Control Panel Type B-3A for B-17s, B-24s etc For Sale

This piece is technically called the "Bomb Release Interval Control" It permitted the bombardier to control the number of bombs dropped per release and their impact spacing. This would be used to set up a carpet bombing run, for example, over a large railroad marshalling yard vs a more concentrated drop over a specific site such as a ballbearing factory. It was made by F. R. Mallort and Co. Inc. of Indianapolis, Indiana. Serial Number 4795. The left dial selected the spacing interval between bombs at a given airspeed, while the right dial selected the number of bombs to be released at a time. The bombardier could also choose to either manually drop the cache by flipping the switch to SEL or otherwise automatically by selecting TRAIN.This controller is in good condition for its age. The toggle switches properly and the knobs rotate as they should. The left bakelite knob has a chip and there is a little rust and surface dirt of the panel. The piece has never been restored or tampered with in any way.I believe this type of control panel was used on most of the USAF WWII bombers as well as the Navy equivalents.
