The Birmingham Proof House Trial Report of 1891 included barrels described as:
1. Belgian and English Laminated Damascus
2. Machine-forged English Best Laminated Steel, 3-Rod and 2-Rod
3. English hand-forged 3-Rod Best Laminated Steel (the winner of the 1st Phase test)
Your barrel is 3 Rod, and by the pattern is not "English hand-forged 3-Rod Best Laminated Steel" which had a much finer pattern
