John Taylor in Puyallup, Washington has done some very fine Martini work for me in the past, putting together a very fine rimed version of a .221 Fireball Improved for me on a small frame Martini, but I have not talked to him in a few years. I am not even sure he is still doing work, nor do I know where you are located and if he might be nearby. Der Ami knew Pat Felix personally and can vouch for him, but, like John Taylor, he may also no longer be taking in work. I would try someone fairly near you, within driving distance, if possible. Personally speaking to your gunsmith goes a long way, IMO.
