You cannot go wrong with Harton, Bowen, Stroh, Clements (I have or have had pieces from them all) or the Linebaugh's, Huntington, Horvath, Gallagher or Forkin. They all substantially specialize in six (and five) guns and will deliver a top notch product. That said, because they all are at the top of their game, patience will be a virtue as you await delivery which is into years for some. A couple, I believe, are not taking work until they catch up a bit.
