I've been watching the original version of the Wolfman, the true story, made in the 30's or 40's, before Hollywood starting putting in all kinds of things that arent' true, and in a scene in the cemetery, a couple of the grave stones are crosses with a semicircle atop them. Running from both outer ends of the horizontal piece and touching the top end of the vertical piece, but still circular. Semi-circular.
I don't think I've ever seen a cross like that since I last saw the movie 60 years ago, but since I know the movie is scrupulously accurate, I thought someone here might know if that kind of cross has a name, or who uses it, etc.
