To change barrels or not.

[URL="http://www.gunbroker.com/Auction/ViewItem.aspx?Item=452199412It has WRA where the handguard covers and a WP in oval but the gas port is VERY shiney. I say chromed. The chromed gas port caused me to pause, but I think its a WWII barrel, but I really dont know. its on GB and was thinking of buying it but wanted to check here before I did. The barrel on the rifle now has a 1 0 and a WP in oval on the muzzle end when the op rod is pulled back. Well, That is the link but I obviously don't know how to do links. Sorry, No one ever showed me how.
