Does anyone know of a source, other than the factory, for barrels, shrouds and assemblies? I believe that either Natchez or Midsouth used to stock the items, but no longer carry them. I have a Model 15-2 with a 4" VH assembly, and an 8" standard assembly. I was thinking of eventually acquiring a 2 1/2" and 6" assembly for a complete outfit (and a case also).
