There is no compelling evidence or 'smoking gun' pointing to a forgery, though there is more than enough information for people to make up their own minds about what they believe.
Someday, perhaps, more of the truth will come out. It seems that one result of living in an 'information age' is that it becomes increasingly difficult to hide the truth and/or the facts. SRF, being such a secretive organization, has much to share in the coming years, willingly or not. I look forward to it.
