Per Recent Digest Topic: I've been hoarding Duquesne's for a few years now because of their unique look, and have had them out and lined up several times trying (hoping) to make some sort of connection between the 106.1's and 106.3 molds. I never could figure out why such uniformity from the upper wire ridge down, yet so much variation from the ridge up. Looking at the Croskey Patent sheds light on the possibilities. As for a connection between molds used; I've studied the five 106.1 and three 106.3 molds in my collection for any connection, and none have match points to date

Good Collecting, Dan
