This is in no way a criticism of what is obviously a high grade gun, but simply an observation that the English barrel makers were having difficulties at least with the esthetics of their crolle damascus in the 1860s. British Laminated Steel was mostly used on higher grade guns after the transition from (true) Stub Twist by the 1850s - 1860s. Thereafter English 2 Stripe and English Best 3 Iron became more popular, and before long the vast majority of tubes used by the English makers, including those in London, were sourced from Belgium.
I took the liberty of enhancing the barrel segment, which is a mess

This is interesting! Daryl sent me this; a R.H. Thomas pinfire with what may be (the first I've seen) 2 Iron "Chequered" Damascus
