Check ebay. They have them all the time. What was your reason for taking it off? The pre 64 barrels were pretty damn good in their own right. I'm assuming your Kreiger shoots better than my 30-06 fwt?
Or was/is there another reason you took it off? Didn't like iron sights on it. Too original for you? Front hood kept falling off...
If your barrel wasn't shooting good or is completely worn out, what is it worth? Check ebay, they sell them from almost brand spanking new to old and crusty with most of the bluing gone. I have a 300wm sightless barrel that doesn't have any rifling left in it. I wonder how much that one is worth? I used it for a pry bar a couple times...
