Tanked

This semi-tracked US armored vehicle was reportedly being tested near Los Angeles (Popular Mechanics, May 1917). It is an awkwardly high conversion of a Holt tractor, and had a tendency to either bog down or tip over!

Tippy Tank

Here is a large conversion of a Holt tractor into a quasi-tank, used for training US Navy recruits in land operations (Popular Mechanics, Sept. 1917). Unfortunately for a vehicle intended for use in rough front line terrain, it was quite tippy, all the weight being very high up.

Super Sleigh

Allan Alexander “Scotty” Allan, one of Alaska’s most famous dog team trainers and handlers, designed this 60hp propeller-driven sleigh. He also trained 450 dogs for the French in WW1 and served in the Alaska Legislature! (Popular Mechanics, Nov. 1917).

Fowl Play

Duck hunting with nets attached to the winds of a biplane (because it was illegal in California in 1921 to shoot wild fowl from a plane!). You needed a darn strong prop for this sport (Popular Mechanics, Feb. 1921).
