Sometimes I visit eBay to see what Jeep items folks out there are putting up for sale. This gem came up from someone in the Toledo area. It's the original artwork used for the Willys MB Water Fording Kit. Thankfully the shots were of decent quality as I was able to clean up the image and fill in the frayed edges and soiling.

An unmodified Willys MB was able to water ford about 21 inches of water before the transfer case vents and fuel pump have issues. Troops in the field were modifying their Jeep 4x4s to survive deep water in their beach landings. This included sealing the distributor and ignition system, and adding an intake snorkel and extending the exhaust system among other things. Willys-Overland engineers were tasked with coming up with a kit to distribute to the troops.

This is just one example of the many ways the Willys MB Jeep 4x4 was modified for use in the field during World War II.

According to cj3a.com it looks like the kit is a MX-735 Waterproofing Kit: "This kit was designed for the Navy and supplied by Willys-Overland for use on Marine Corps CVD radio jeeps. The kit also fit on the G503, W.W.II jeeps. It consisted of numerous parts to be installed on the jeep to make it waterproof. Everything from a new dipstick to a new speedometer were included in the kit. The distributor was replaced with a waterproof metal clad unit. The spark plugs and wires changed to waterproof "aircraft" type. A waterproof Carter YS carburetor replaced the standard WO carburetor. Fittings and vent lines were included to allow an atmospheric vent system to be attached to the transfer case, master cylinder and fuel tank. Two valves activated by a control on the dash allowed the engine crankcase to be naturally pressurized slightly while fording. The electrical system was upgraded with waterproof generator, regulator, starter, switches, horn and wiring. This must have taken a considerable amount of time to install, but when completed, the jeep was always ready to ford, unlike the earlier WV-6 kit."

Willys Quad Capitol Steps

Contrary to popular belief, the name “jeep” does not derive from “general purpose.” The name likely combined two elements. The first was the extraordinary “Eugene the Jeep” character from the Popeye comic strip. Able to do extraordinary things, and do anything. The second came from military slang for any unproven piece of military hardware, human or mechanical. In early 1941, Willys-Overland staged a press event in Washington D.C., having the Quad drive up the Capitol steps. Irving “Red” Hausmann, a test driver on the Willys development team had heard soldiers referring to the Quad as a “jeep.” Katherine Hillyer, a reporter from the Washington Daily News picked up Red’s usage of the term “jeep” and printed the headline “Jeep creeps up Capital steps” — forever fixing the name in public awareness.

1940 Jeep Willys Quad

In June 1940, with World War II on the horizon, the U.S. Army solicited bids from 135 automakers for a 1/4 ton “light reconnaissance vehicle” tailored to Army specifications. Only three companies responded – Bantam, Willys, and Ford – but, within a year’s time they collectively produced the template for the vehicle known worldwide as the “jeep.”

Willys-Overland delivered the prototype “Quad” (named for the 4WD system it featured), to the U.S. Army on Armistice Day (Veteran’s Day), November 11, 1940. The design was completed in a remarkable 75 days.

Only two prototypes were made.
