I enjoy reading your posts. I used to have an acquaintance who was a jeweler with an interest in guns. I always thought that his skills at putting small bits of metal together, and putting fine finishes on metal, would translate well to gun work. Your experience as both a watchmaker and a gunsmith seems to confirm that you can definitely apply skills with metal in tight spaces, and with small turning parts, in both directions.
I think your point about being a business man first, and a gunsmith second is very important.
