The miniature road roller is #1 in the original 1-75 series.Released as a three-model set the other two miniatures were a dump truck and a cement mixer. Recreations of these and other early Matchbox cars have been released.(This accomplishment must be put in its historical perspective: Basically, the series "re-wrote the book" for small die-cast car models from 1968 onwards, forcing the competition at Matchbox and elsewhere to completely rethink their concepts, and to scamper to try to recover lost ground.) Harry Bentley Bradley did not think that would be the case and had quit Mattel to go back to the car industry.
From 1947 to 1953 the company manufactured larger die-cast vehicles and other toys to market to the London shops for Christmas.
It was the combination of all of these ingredients — speed via the low-friction wheel/axle assembly and racing tires, looks due to Spectraflame paint and mag wheels, plus the inclusion of very American themes such as hot-rod designs based on true American prototypes not seen in great numbers in the competition's product lines — that laid the groundwork for the incredible success story Hot Wheels were to become.
As it turned out, the Hot Wheels brand was a staggering success.
During the fledgling Hot Wheels era, Mattel wanted to make sure that each of the cars could be used with any of the play sets and stunt track sets.
Unfortunately, testing showed that this early version (now known as Rear-Loader Beach Bomb, or RLBB) was too narrow to roll effectively on Hot Wheels track or be powered by the Super Charger, and was too top-heavy to negotiate high-speed corners.
