What part of "Harvey & Lee"? The notion of two Oswalds goes back long before John Armstrong's research. Furthermore, you're claim was in the plural and this would be just one.
The exhumation of LHO in 1981 debunked the 2 Oswald theory of Michael Eddowes. It also debunked H&L before it was even devised. I have over twenty articles that help to debunk minor theories associated with H&L. But you don't need to ask me about this here (unless you are just trying to start something), you can read the articles and judge my work for yourself. Thanks for your interest.
