I have a SA 4-18 barrel on my 1918 m1903. I purchased the barrel to replace a worn out barrel that was on the reciever when I got it The barrel is marked with a P and a J66 on the lower portion, and SA on the muzzel with the ordance symbol and then the date below that. What it also has is a capital A centered below the date. Looks like below:
Any ideas what that means?
