are a few additional mounts developed for specific vehicles or purposes.
The D67511 and 7058824 folding pintle bracket mounts were the solution of
the Aberdeen Proving Ground to the problem of the anti-aircraft weapon for the
M8 Armored Car. Though supposed to replace all other interim solutions, such as
the ring mounts installed on many vehicles in Europe, there is very little photographic
evidence that these were actually in use before the end of WWII.
5460258 (D60528) and D94478 concentric ring mounts were complete assemblies
in which the cradle was attached to a vertical support that, in turn, was attached
to a ring that rotated inside a larger ring. These were used mainly on the M18
76mm Gun Motor Carriage, the M8 75mm Howitzer Motor Carriage, the M7B1 105mm Motor
Carriage, and the LVT(A)4 Amphibious Tractor.
8c and 8d
7069693 cradle and pintle assembly (fig. 8c) was basically the same
as 7068880, but incorporated mounting tubes for the attachment of an armored shield.
It was used with shield 7069692 to form the 7069694 (M69E) shielded bracket mount
(fig. 8d) which equipped the LVT-4.
