parker damsacus steel blade count/pattern type

[bruce willis]

how can you determine parker Damascus steel blade count/pattern type. On the 12 Gauge barrels I'm looking down at the barrel flat, muzzle's to the left, there is a upper case D on the lower left, little above that and little to the right a C, then to the lower right a 3 15, then to the far right next to the chamber ends the are + signs on each barrel. I'm unable to post photos. Information on this topic would be appreciated, thanks,

And then of course, there is the fabulous commentary in the sub forum titled “Damascus Barrels & Steel“ in the section for non-Parker specific & general discussions that is devoted to Damascus and all the other composite ferrous metals history and issues that come to mind for the forum members.
