Have you ever wondered just how many Hercules and related engines are still around? Some 400,000 were manufactured over a 20-plus year period. It is likely that we'll never know how many are still around; however, quite a number are known. There surely must be several thousand more out there that yours truly hasn't seen or heard about. For the past ten or twelve years I have been gathering information on the Hercules and related engines. Following is a somewhat haphazard breakdown of those known at this time.

Again, it should be pointed out that these are the ones that your author has learned about over the past ten or so years. There are many more out there. If you have engines that you wish to add to the list, you may send the HP, model (letters after HP) and the serial number to the address above.
