It's very common for a lot of European guns to have Krupp barrels. German guns of course used a lot of Krupp steel and would be the most common makers to use Krupp steel, but you'll also find Krupp steel used in barrels of Austrian and Belgian guns and others.

The use of damascus barrels on guns began to decrease pretty rapidly after 1900, although they were still fairly common up until the start of WWI. If you have a breech loading gun with damascus barrels it will probably date from 1875 - 1910. Most damascus barrels on U.S. guns seem to have actually made in Belgium. There is a lot of debate as to whether any damascus barrels for shotguns were actually made in the U.S. It seems likely there may have been small numbers produced in the U.S. However, Belgium had a large gunmaking trade at the time, with a lot of barrel makers specializing in damascus barrels, so it was generallly cheaper to import them than to make them.
