It's this bit that had me LOL:
"Contrary to some opinions expressed to me, this is not a joke. I have started researching as best I can to get some positive identification. As yet I have none. Untill then I absolutely believe it is what I say it is, as has been believed to my knowledge, for at least the last 140 years or so. If I find any positive evidence that I am correct in my belief, I will be asking a higher price. So far all I have discovered is, it is more than possible."
