As I had stated earlier the Kerr would be correct for the WWI era which is when it was first adopted. If you're looking to make it turn of the century correct you're going to have to choose between a M1907 or M1887. I have a repop Kerr on my US Model 1917 and it's excellent. Truly a marksmans sling and very easy to reconfigure. No wonder the Marines adopted it in 1917.
