Damascus Pattern Question:

[Bruce P Bruner]

I would like to identify the pattern on these barrels. What I think I see is the "Oxford Three Iron Crolle". The "riband" welds are somewhat nondescript. The stars look more defined than the Oxford pattern, almost similar to the four iron "Turkish Star" pattern. There are so many variables in the construction of these barrels it's difficult for me to make a positive identification. My best guess is "Oxford Three Iron Crolle".
Can you imagine the manhours necessary to complete of one set of barrels?
