Ok, we admit we’re not the sharpest tool in the shed; the brightest bulb in the room or even have all our bricks for a full load, however we do try and make ourselves a bit smarter each and every day. We call’s it “book lerrning”. So in part of this “education” we’re undertaking we’ve tried to list the various motors HD manufactured and the years they did so. Comment if you think we got it right, or wrong. But be gentle.
