Does anybody know the size and thread pitch of the screws that are used as index pins in Copal 0 and 1 shutters? Additionally, are the holes for the pins in the shutter blind, or do I need to worry about screwing something in to the point that it snags a moving part, and if so, what is the safe depth of the hole?
