|Some identical Models may have different Manufacturing numbers. Like
#66 KENWORTH Super Boss and #84 KENWORTH Bandag Bandit.
In those days (1982-1984) Matchbox issued different MAN numbers for the same castings if they were part of the same range at
different numbers at the same time (in this case it was number 65 and number 66 in the US range).
The same also happened with the Corvette which was both MB 062 and MB 115 (US issue numbers 62 and 21, respectively) and with the Red Rider
which was both MB 086 and MB 126 (US issue numbers 48 and 67, respectively).
Matchbox stopped doing that in 1985 when the
MB 137 F1 Racer was also part of the US range twice (numbers 6 and 65) but was not allocated a second MAN number because of that.
