It is the orginial barrel? What kind of finish does it currently have? Look by the front sight there should be an ordanance stamp with the date the barrel was made under that, under the date should be the initals of the manfacturer, Many of these rifles were rebuilt during WWII. If the barrel is a WWII vintage, you've got a rebuild, it will also be parked. (so will the receiver, triggerguard) The orginial finish was a dull blue both on the barrel and on the receiver, triggerguard. (not sure about the bolt) IF it is a rebuild, Take the action out of the stock and check the front receiver ring for cracks, Some of these receivers cracked when being rebarreled during rebuild,(I believe this applies to Eddystones) I suspect most never got out of the armory and I also suspect a very few ever cracked in the first place, but, it is a remote possibilty, I'd check anyway. If on the other hand it is all orginial, It is a Winchester, and seeing how ther are going to fold up shop soon, your friend might have a soon to be valuable rifle,well worth the effort of restoring. I'd research this rifle carefully, and take a inventory of what parts were/are orginial and see if you're missing anything,and try to find orginial replacements. there alot of chinese fake parts being sold so be carefull
