Kirk and myself are the only two offering sleeving in the US I’m aware of. Not sure if Hugh Lomas or Hosford are still in the game? Like him, my backlog is LONG. Expect around $3000-$3500 from both of us.
For whatever my opinion is worth to anyone, Mr. Little (gunmaker) sleeved one barrel of a 32" Elsie Specialty for me and did a fantastic job. The right barrel had blown out sometime in the past on the gun and Pete Hiatt (sp?) had fitted a shorter OO grade barrel to the gun, but still had the original set with the blown tube. gunmaker's sleeve was completely seamless and perfectly matched the other tube of the set. I lucked out getting an introductory price from him when he first began doing this work...Geo
