	There are a few serial numbers that don’t fall into the apparent groupings. I believe these are due to having to replace a switch after the fact, maybe an odd switch being left at the bottom of a bin at the factory and for some reason being the one that they reached for in the factory or the machine being preassembled and not given a serial number until it went out the door.
