Spec. 98-24105-R, September 20,1943, adds markings for battery location and changes radio call number size and color for night fighters

When Spec. 98-24105-R was issued on September 20,1943, it added a new requirement for battery location marking. This required that the following marking was to be placed on the left side of the fuselage or tail boom as viewed from the rear of the airplane, using either a stencil or decalcomania, to permit the disconnecting of the battery on crashed airplanes by inexperienced personnel:

BATTERY LOCATION……………………….

The fore and aft location of the marking was to be approximately in line with the trailing edge of the wing. Its vertical loca­tion was to be 2 to 3 feet off the ground with the airplane in the wheels up position on the ground, or for airplanes with fixed landing gear, with the landing gear washed out. If there were windows in the prescribed area, the marking was to placed as close as possible to the desired area.

A new requirement for the radio call number on night fighters reduced their size (to an unspecified dimension) and changed their color to Insignia Red No. 45, Bulletin 41.
