AUTOCAR GASOLINE TRUCKS, 1921 Gift of the Autocar Co. in 1 922 (USNM 307255 and 307256) These one-quarter-size models represent the type XXVI-B (fig. 99) and XXVI-Y (fig. 100) Autocar trucks of 1921. Except for the wheelbase and the type of body, the two types are identical. The former has a 156-inch wheelbase and a unit construction rack body, while the lat- ter has a 120-inch wheelbase and a rotary dump body with power hoist. The wheels of the larger model and the dumping action of the dump body truck were originally operated by con- cealed electric motors. Otherwise the models are inopera- tive.
