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.
