Canada built and used trailers with her military vehicles.
In WWII the sizes were by hundredweight (Cwt.) which equals 112 pounds.
Thus: 10 Cwt. = 1/2 Ton (jeep and small truck size).
Canadian built 10 Cwt GS trailer in action.

Trailer, 10 Cwt. 10-P-GS-1 Composite wood and metal construction. Made in
Canada. The lunette is reversible so that it can adjusted for a high (e.g. 60
Cwt. - 3 Tonner) or low (e.g. jeep) towing vehicle to help keep it level.

Trailer 10 Cwt, GS Code 10-P-GS as made by Willys-Overland. From
Dr. Bill Gregg reprint of a 1944 Vehicle Data Book of the Canadian Army.
Willys MB-T trailer from reprint of a WWII US manual on the jeep and trailer.
Trailer MB-T made by Willys in the USA during World War II. This is a 1/4 Ton
trailer towed mainly by jeeps. It is 6 volt electrical system (M100 had 24 V);
has NO corner handles (those came on later M100 trailer in 1950s); and NO
tailgate (those came on Civilian T-3C trailers). Tires are 6.00x16 on
"combat" (split) rims. During WWII Bantam also made virtually
identical trailers. These are called the Bantam T-3 (NOTE: The T-3C is
CIVILIAN post-war). These were classed as 10 Cwt by the Canadian Army in WWII.
1 Canadian Parachute Battalion was part of the British 6 Airborne Division and
as such used some 10 Cwt Lt. Wt. trailers e.g. for Mortar Platoon and Medical.

as a set of 8 volumes published in 1945. These scans are from my originals of
the next edition - a 2 book set published by Directorate of Vehicle
Development, QMG Branch, DND.
Canada used and built many other trailers. The above are just some of the
most common WWII types.
