Davis Needles
OK, a friend brought over a collection of "old sewing stuff" today to give to me. I'm always looking for interesting things. Anyway there is a wooden tube of 6 Boye needles in here. They are just a hair short of 2" long and each one is marked "Davis SM" and "0" on three of them, and one each of "00", "1" and "2". The cap of the tube says "8" and below it "30 - 80" and "4-5-6". very sharp, I would guess new.
What would these go to?
