If it were an aftermarket upgrade by Simmons the rib would be marked as a Simmons rib. RTF Obviously the gun was repolished prior to reblueing after the rib was installed which accounts for the stretched stampings and Phillip acknowledges it was an upgrade and most likely subbed out to Simmons or Moneymaker to do the work. Its nice gun but as Phillip already knows it is not original, however, simmons guns are picking up some interest as of late due to the scarcity of originals.
Phillip you might contact the people at Cody to see if they have any of the old Winchester records.
