6 D69820 (6569820) CRADLE AND PINTLE ASSEMBLY
Often referred to as the
early style mount for the M4, this assembly, like the later D80030 assembly, was
designed to allow the gun to be positioned several inches forward of the trunnion
in order to clear the hatch opening. A spring-loaded cam allowed the main bracket
to be locked into two different positions, giving two ranges of elevation. It
was usually fitted with the D68375 50-round ammunition box, and was originally
designed for use on the M7 105mm Howitzer Motor Carriage and the M4 Medium Tank.

Picture of the D68375 ammunition box normally used with the D69820 cradle
and pintle assembly. The two prongs on either side of the lid snapped onto the
small bosses visible near the corners of the box itself. This was done to keep
the lid from flopping up and down during movement when it was open to permit the
ammunition belt to be fed into the machine gun.
