The North American automakers kicked their production lines into high gear to produce military trucks during WW2. The Canadian Military Pattern trucks were manufactured and then partially disassembled for shipping overseas. Most went to England where they were put back together in a number of factories spread around England. In many cases the cab and bare chassis arrived and were completed with whatever body was required before being shipped out to their ultimate destination.
Some were shipped directly to where they were needed, and assembled by whatever skilled and unskilled help could be rounded up. There were several variations for knocking them down all with their own army-specified name.
The Delta plan was one chassis plus cab in a crate, a second crate held two bodies. This method was the most dense way of packing, and required the cab and body (box) assembled, axles springs and drive shafts installed, brake lines connected and bled, it took more time and required skilled help. This method was generally used when reassembly was done in the Canadian-run reassembly plants in England.
The one pictured here is the Alpha method, used for assembly in the field. The wheels and top half of the cabs were removed and the parts shipped in one crate. (No mistaking who made these!). When they arrived at their destination- these pictures apparently taken in Egypt- wheels and steering wheels were fitted and the vehicle rolled away to have the cab finished. Quick and efficient.
The other methods also specified more assembly due to smaller more densely packed crates.
Beta 1 had the chassis in a crate with wheels removed, the body (box) inverted over the chassis and two cabs arrived in a separate crate.
Beta 2 came back to one vehicle per crate with the cab split into multiple pieces. These methods applied to the GS (general service) trucks, specialized vehicles had their own specific shipping methods.
During the war years between 1940 and 1945 Canada produced and shipped overseas more than 88,000 trucks.

A 1979 ad from Honda, from their short lived 23"front wheel era.Without mentioning the tire manufacturer, they are expounding the advantages of their new offroad "Claw Action" tire concepts.
As far as I know the manufacturer was actually Bridgestone, and the tires failed to revolutionize offroad riding.
In business from 1909 till about 1940, the company's heyday was in the 1910s, selling mainly to women and people who did not want the hassles of handstarting a gas engine. The maximum speed was about 20 mph and the range about 80 miles. The name was changed to Detroit Electric Car Company in 1920. About 13,000 were built in total.

These 1942 photos show testing by the Germans of a rigid tow-bar for glider launching and towing. Experiments with a bar 1 to 10 meters long were tried successfully. The method allowed safer nighttime operation. The practise never became widespread as the JU 52 towplanes required strengthening of the fuselage and they could not afford to be taken out of service for the time required.

When it needed replacing, the end sections were replaced by fill while the centre portion was replaced by a 600 foot steel bridge.
