Found the Pietta Manual, excellent thanks for suggestion.

The club is not specifically BP but several shooters do have revolvers so they'll put me right. It was rather to find out about the quality because I don't want to make another "Mistake". I bought a genuine Colt Navy 2nd gen which was unfired. When I found out it was one of the very first (Made 1971 and assebled at Hartford), I just couldn't bring myself to shoot it..... It's sitting there in it's box 53 years old and still unfired.
