It is not uncommon for builders of contemporary muzzleloaders (flintlock) to create a damascus-like pattern on modern steel barrels using a bleach solution, then browning the barrels overtop this. The bleach adds dark stripes to the metal that if done correctly appears like damascus. However, if a barrel finished like this and a true damascus steel barrel are compared side by side, the fake will jump out at you. I believe Lewis Drake had one of these on his website a while back.. He may still have it.
