Big-Bang Model 60MM |
|
Introduced in 1958, the Big-Bang model 60MM is based on the 6F one-piece casting, substituting
rubber tires in place of the iron wheels.
Two types of tires were used.
The earliest ones were marked "Premier U.S.A. 1100 X 20" and have a military tread.
The later tires are un-marked and have a tractor style tread.
This 60MM has the Primere tires.
This example shows the tractor tires.
