R. Jackson, the official Ordnance Department observer: "The three (3) Four Wheel Drive Trucks were, in general, the most satisfactory in the Convoy and of all of the various makes represented, the F.W.D.'s alone were able to pull through all of the bad, muddy, and sandy stretches of road in Nebraska, Wyoming, Utah and Nevada absolutely unaided." (emphasis in the original.) A Canadian subsidiary was set up in conjunction with Dominion Truck of Kitchener, Ontario by 1919. A British subsidiary was set up at Slough in 1921. In 1926, the British FWD, also known as the Jeffery Quad, was produced with a larger 70 bhp engine. A relationship with premier race car constructor Harry Miller resulted in the Four Wheel Drive Miller that competed successfully at the Indianapolis 500 in 1931 and later. This car was intended to demonstrate that the advantages FWD's lockable center differential were not limited to off-road driving. One example survives and has competed in premier vintage race car meets such as the Goodwood Festival of Speed. "The Last Great Miller" by Griffith Borgeson gives a complete history of this landmark car. In 1932, AEC took a controlling interest in the British company and began to use more standard AEC components in the Slough-built vehicles. To distinguish these from imported U.S. FWD vehicles, they were marketed under the name Hardy. Production ceased about 1936, but AEC exploited its experience with all-wheel drive in its Second World War Matador (4x4) and Marshall (6x6) vehicles. In 1939, the company formed a flight department. Their acquisition of a used Waco biplane would eventually evolve into North Central Airlines. In 1958, the company's name was changed to FWD Corporation. In 1963, FWD acquired Seagrave Fire Apparatus who then moved from their old location in Columbus, Ohio, to their current location at FWD in Clintonville, Wisconsin. Many tower ladders in the 1990s using Seagrave chassis were branded as FWD. They used Baker Aerialscopes for the boom which FWD had also acquired over the years along with Almonte Fire Trucks. Randolph Lenz, chairman of FWD's parent company, Corsta Corp., became embroiled in a Federal Deposit Insurance Corporation suit, and in 2003 all assets of FWD, FWD Corporation, Seagrave, Baker Aerialscope, and Almonte Fire Trucks were sold to an investment group headed by former American LaFrance executive James Hebe. Today, the Seagrave Fire Apparatus group is a flagship company of ELB Capital Management.
