Hi Keith - if you come up short in getting the Curta screws replaced, try contacting Jack Christensen at chronos@northshore.net . He is the only man left in the U.S. that I know of who still works on Curtas - no idea if he would have the screws (I've been told that they are unusual but I don't know that for a fact) but I know he'd be happy to help if he can.
