Has anyone come across a screenplay for an adaptation of Conan Doyle's "Hound of the Baskervilles" on their travels around the net?

Ideally the 1930s Rathbone one or the 1950s Hammer version, but any would be welcome (except the 1970s spoof Cook and Moore one!).

I am not fussed as to format - pdf, text, doc - as long as I can open it and read it!

Your help would be greatly appreciated.
