Thanks for explaining the issues. I thought that someone in years past had posted on Kurt's Chan Message Board something about copyright issues regarding the lost films, and that ownership might be in dispute if one of these films were now found, but I don't remember the details. I suppose we will find out about all of the legal angles if we are ever fortunate enough to find a lost Chan film.

Thanks for your response, Steve. I'll try to track down those six Biggers novels.
