In 1989, Imperial Schrade presented a line of special factory order knives to Cotter Company, the owners of True Value Hardware chain. Their original plan of twelve items was accepted. Anticipating a large order from Cotter, some of the components for some patterns (MM18, MM152, MM8) were sent to Camillus for assembly.

And an additional promotional item, the MMS7, SP7 Lightweight lockback.
During 1991, blade etching began, instead of the special tangstamp and shield being used. The MMS7, MML7 and MM152 were discontinued, and the orange handled MMT1, MMT3, and MMT4 were substituted.

As you can see, the regular production Schrade name brand knives were sold to Cotter before and after the private labeling, and likely during as well. So seeing one in a MM box is not odd at all. Note that productions/deliveries did not begin and end on January first, so we might best say "the MM152 was produced only circa 1989-1991". Less that a three year run, no doubt, makes this particular one a uncommon SFO for the Sharpfinger pattern collector.
