Specific: The Canadians made a post-war upgrade
on some NM´s, comprising new Mack commercial cab,
headlights, enlarged brush guard.etc. Some were donated
to the French Army, and it is most likely the that Danish
vehicles came from the same batch. 2 such vehicles were
procured in the period 1954 to 1957 via the MDAP.
The shown vehicle was used as a chemical lab used to
determine types of chemical agents used on the
battlefield. The trailer, which is a M104, contained a
JAP generator set and other material. The body appears to
be locally produced.
It is not possible to determine the exact
designation of the vehicle. Due to the fact that a pintle
hitch is mounted at the front, the vehicle is in the NM-4
to NM-8 range.
The 2 vehicles were finally disposed off in
Historical: Mack´s first military 6 x 6 (NM-1)
appeared in early 1940. The QMC initially ordered 87 which were cargo/prime
mover trucks intended for hauling AA guns and crews. A second order for
107 units, designated NM-2, followed in February 1940. Corbitt had developed a similar model,
sharing the same transfer case and axles. Mack used its
newly introduced Commercial L model cab. Engine and
gearbox, too, were Mack´s own.
In 1941 further 104 NM-series cargo/prime mover trucks
were produced. Compared to it´s predecessor, the NM-3
differed in several details. It was the last of the NM´s
with an enclosed cab, later models having the soft-top
With the US involved directly in WW II, the NM became
available for defence aid (Lend-lease). Now designated
NM-5 and NM-6 the trucks were given a soft-top cab with
folding windscreen for tactical reasons, and to simplify PKD shipment to save valuable shipping
Main recipient was the UK with 2.382 delivered.
As the war went on further trucks were required and 2 new
batches, the NM-7 and NM-8 respectively, were produced in
1944 and 1945.
After the war ended many NM´s went to various other UN
