Hey Tom, sorry I have nothing to offer but I am currently working with a couple of Elgin pocket watches. I rather enjoy working Elgin because as a beginner I find them to be as of my taste. My future intent is to get to where you and the others are already at. Best of luck with your situation and I will keep-up with this topic, only as a spectator and not a consultant. Thanks for this very interesting topic. Ed…..
