Warbird Information Exchange

Available for sale or trade is landing gear audible warning signal. It carries part number AN5775-4. Not sure what warbird this was intended for, but this component came in a box of -4 Corsair parts...but think this may be a generic part for several aircraft of the time period. Any ideas on a specific aircraft this belongs to?

Drawing for AN5775 was approved on March 28 1942 and inactive for new design or procurement after July 2 1945. It was replaced by AN5776 which has a different mounting arrangement.

AN5775-1 was 12 volts and AN5775-2 was 24 volts. There is no -4 on the specification.
