I have been following all your threads on the various shotgun bbs forums. Thanks. I have a 0E grade with the 3 or 4 iron crolle pattern. On p.74 of Brophy's book ( I have yet to get the Legend Lives ) he lists the 0 grade as having 'damascus steel'. I also recently came across a grade 2 gun. It has the visible 'chain' pattern as offerd as being an option on p.69 of Brophy's book. However on p. 150 of the same, Brophy gives the declension of Damascus steels and neither "damascus steel" nor "chain damascus" are mentioned in the list. Where do they stand in the list? Is the 3/4 crolle or chain pattern better? I regret I do not have digital capability. Thanks for your time and research.
