Thanks for the link to your site. I am familiar with your excellent work with silent films.
Were you also a student of WKE? I was privileged to study under him (and Jay Leyda) at NYU in the late seventies and early eighties.
I think you are right. I do seem to remember that there was a copy of DOMBEY AND SON in the WKE collection. I'll look into it.
It is frustrating, though, when you know that prints of this thing -- including 8mm and Super-8 -- must be out there!
By the way, you might be interested in the January 10 article on my web site that quotes WKE on DOMBEY AND SON. It includes a plug for his AMERICAN SILENT FILM See:
