Molds used in the previous generation of Mini-Jectors built from 1946 to 1987 (including the Model 40, Model 40A, and old style Model(s) #45 and #50) came in two sizes:

• 4.5" long x 2.625" high
• 6.0" long x 2.625" high (current Mini-Jector part number 121230)

These molds can be used without any modification in any of the current "Wasp" Model(s) #45, #50 and #55.

If the current machine has the wide mold option, the smaller mold would require the use of the factory-supplied adapter.
