Chuck,
I thought you might be able to use this in your catalog. These are just some of many uses for thimbles.
Photos: 4b, and 4c is a snotter for a sprit sail found in Pete Culler's book Skiffs and Schooners, photo 5h is just a thimble with a tail that can be used as a dead eye or a cunningham or a half a dozen other uses.....
