Cilla,
Sorry that I missed your last reply to the thread. The holidays made it a bit crazy around here.
What you appear to be saying is that the parts other than the barrel has been reblued? Is the barrel still original color? Or is there two different reblueing color?
Old, all original, used Winchester rifles commonly have a different bluing wear pattern betwween the barrel and the receiver. The metal composition is different for the parts and the bluing adheres differently as a result. The fact that your receiver is darker than the barrels is a sure sign that something is amiss. It does look like the barrels are original blued.
And you are saying that because of the wear on the wooden parts there would definately be wear under the ring?
Yes definitely. It would be impossible to have that amount of wear on the wood as this rifle has and for there not to be a worn area under the saddle ring. They typically will look like the photo below. I obviously can't explain when or how it was done but it has definitely been reblued.
Thanks for your interest.
