Hello there John, & Welcome to our Forum! Unfortunately, your serial number falls into two time period ranges. On the early side, it could be from 1898, OR it could be as recent as 1918. Your question is much more condition dependent than age dependent. Are the barrels Damascus or Twist? Have you had the minimum barrel wall thickness and condition checked by someone who can actually perform those tests? We've got lots of members who can do that for you, if you're close enough to reach out to them. Let us know from where you hail, and we'll go from there. Once again, welcome! John
