I'm not understanding the reasoning or logic behind this thought process. The barrel is dated 6 - 18 with all the stamps that a Winchester M1917 would have in WWI service. If it was a post war rebuild then why use an old barrel if most used the Johnson Auto barrel... I realize I'll never get the perfect answer as there are no records. No matter how it ended up miss matched, for $160 I'm counting it as a lucky find. I can't wait till friday when my dad brings me the possible 1917 bayonet. I'll have a new history endevore for the weekend.
Thank you for all the comments guys! This rifle has really sucked me into the history...
