The plot of The Ghoul kind of reminds me of the plot to The Hound by Lovecraft. In that two guys take to grave robbing for the fun of it and morbid fascination. They grab some sort of artefact from a dead dude and are hunted by a horrible creature.It doesn't look like it's here, but there are many versions of frankenstein out of copyright you can find here, including edisons 1910 silent film version:
