I went out to the shop and stripped the 1873 down to receiver and barrel.
  Need to remove the barrel to put it into the lathe to bore it out. I was extremely concerned about removing a barrel from a 128 year old gun. But I put the barrel into the vise, attached the receiver wrench and with about 20 pounds of force the barrel simply popped right off! NICE! 
 I also received my Cody Museum letter. It's posted on the web site.
