I have one of these Bowkett 127s and as you say it really is a sweet shooter. But after 25 years of service it is now down on power and I face the dilemma as to what to do with it: Should I replace the Bowkett seals with a standard seal or is it still possible to obtain or make the Bowkett seals? John Bowkett really is a terrific gunsmith and was years ahead of his time.
