I got a barrel in an estate still wrapped in the shipping material. It looks to be from many years ago. It is from the rock island armory commander. (Shipping label) Looks to be 30/06 as this fits the chamber. No real marks other than a j. P. At the muzzle end. Milled for a sight.

Thread outter diameter is 1.25”. Threaded end is about .8

What was this barrel. Did the rock island armory sell new Springfield barrels?
Is it worth something?
Thanks. I don’t know what to do with it. Hate to scrap it if it is worth something to someone.
