According to Wikipedia, all 14 “Chapters” of this film serial are extant. Sadly there has never been a complete home video release of the series. All I’ve been able to locate on DVD is the first Chapter, “The Clutching Hand” available (apparently with French intertitles) on a disc called Pearl White: Queen of the Serials on the Grapevine label, which is listed below. Several Chapters have also made it to YouTube.
