Roger, you've got a few years on me for curtain, but I have already thought of the question...How long am I going to be able to work? My intentions now, at 63, is to build 'til I can't. In that department, I have laid up parts sets and inventory to keep me going for quite a while, and I am taking a page out of Brian Dancey's wonderful book, and continue to accumulate more. Over my lifetime, I have been inspired by many types of muzzle loading guns, and I'd like to have one of each. Yes, it's probably not possible, but I'm willing to try. You have a gift and should milk it for all it's worth. You have to have a reason to get out of bed in the morning. I can't think of one much better.
