The only issue I would take with what has been said, is that the men in the past had virtually no tools other than a lathe, basic hand tools and the tools they made. The modern gunmaker has many more modern tools to avoid the laborious hand labor that was so time consuming in the past[e.g. CNC Machines etc]. There is still plenty of hand labor in fine gunmaking but not nearly as much as in the past.As a result I find what they did, with what they had, amazing given the results. Just my opinion Jerry
