  The patent on my Compound seems to date from the
mid-1920's some time so its not the original patent. I can't
find this patent on the European patent site. It may have a
reference to the original patent in it.
  The European patent site I use does not seem to have
patents from before about 1985 on it. Perhaps I don't know
how to work it or maybe there is a better site.
