SmilinSam 3,582 Posted July 12, 2001 The decals were different, the newer had a bumble bee on the sides of the cowl, the hood decals on the old were a whitish decal with silver outline while the newer was more silver and blackwith different lettering. The brake setups were slightly different. The grill on the old one was more like a overlapping woven mesh while thje newer was a square hole grid pattern. The grill emblem on the old was a raised diamond, while the newer was a square AC logo. The rear lift on the newer ones had a re-inforcement ring welded where the lift rod goes onto it, the older did not. the safety decals were a little different. The older used a model 23D 9 hp engine while the newer used a model 243431 10 hp engine. There might be more I could have forgotten. Sam Share this post Link to post Share on other sites

Kent 435 Posted July 12, 2001 Here's some more minor differences, gathered from the 1967 brochures. In addition to the engines, these "late" models have these differences: -- The Bumblebee logo was first used, and quickly identifies these "late" B-10s from the early ones. All B-12s have the bumblebee . . . -- Model ID plates were first used in the grille, in addition to the AC logo plates. -- The engine and drivetrain are now painted black, instead of yellow. -- The backrest on the B-10 is now taller, while the B-12 uses a totally new, different seat. -- B-12 also uses a new black steering wheel, while the B-10 steering wheel remains white. Both have a chrome center cap with the Allis-Chalmers trademark. -- A quicker (5.1 to 1) steering ratio is now used. -- New, heavier front axle and spindles, and wider front wheels with 6:50 x 8 tires on the B-12. -- New, longer choke and throttle levers make it easier to precisely operate these engine controls.
