Special body, carrying tools and machinery for doing repair work to harness, personal equipment, etc., and capable of being mounted on either F. W. D. or Nash four-wheel-drive chassis.] Special bodies were manufactured by these concerns: American Car & Foundry Co., Berwick, Pa. J. G. Brill Co., Philadelphia, Pa. Hale & Kilburn Corporation, Philadelphia, Pa. Dumbar Manufacturing Co., Chicago, Ill. Pullman Co., Pullman, Ill. Kuhlman Car Co., Cleveland, Ohio. C. R. Wilson Body Co., Detroit, Mich. Insley Manufacturing Co., Indianapolis, Ind. Lang Body Co., Cleveland, Ohio. Heil Co., Milwaukee, Wis. Variety Manufacturing Co., Indianapolis, Ind. J. E. Bolles Iron & Wire Co., Detroit, Mich. The first contract for these trucks was placed on August 18, 1917, and 9,420 were shipped to the American Expeditionary Forces overseas by the date of the armistice. It required considerable time to work out and perfect all the details of the special bodies and equipment, as most of these were exceedingly complicated, and in a number of cases there were as many as 700 items of equipment on a single truck. Representatives of the allied governments were not hesitant in asserting that the line of artillery repair trucks developed for our Army was the most complete and well worked out in detail that any army ever received. These manufacturers did the work of turning out the special trucks: Nash Motors Co., Kenosha, Wis. Four-Wheel-Drive Auto Co., Clintonville, Wis. Mitchell Motor Car Co., Racine, Wis. Premier Motor Corporation, Indianapolis, Ind. Kissel Motor Car Co., Hartford, Wis. Hudson Motor Car Co., Detroit, Mich. National Motor Car Co., Indianapolis, Ind. Paige Motor Car Co., Detroit, Mich. Commerce Motor Car Corporation, Detroit, Mich. White Co., Cleveland, Ohio. Dodge Motor Car Co., Detroit, Mich. About 4,000 of the 5,000 special body type of trucks were delivered before the middle of December, 1918. TRAILERS. There were developed five different types of four-wheeled trailers. Each type, being for a particular use, required a special study and individual design, with all the consequent specially prepared machines and specialized shop work. For antiaircraft service, a 1½-ton and a 3-ton trailer were worked out; for the 75-millimeter field gun, a special 3-ton trailer; for the mobile repair shops, a 4-ton trailer; and for the small tank, a special 10-ton trailer. By the middle of December, 2,157 of these trailers had been delivered of the 4,847 that had been ordered and put in production. Concerns engaged in turning out trailers were: Sechler & Co., Cincinnati, Ohio. Trailmobile Co. of America, Cincinnati, Ohio. Ohio Trailer Co., Cleveland, Ohio. Grant Motor Car Corporation, Cleveland, Ohio.
