Very weird

Despite being known for small engines, Briggs and Stratton was a major manufacturer of OEM and aftermarket automotive parts until they spun that segment off into Strattec in 1995.  One of their most profitable ventures was ignition switches and lock cylinders, and this is a blank that would have came with a Briggs and Stratton lock cylinder for a Ford/Lincoln/Mercury vehicle.
