The gun is Belgian, or at least the barrels are. In the period 1880-1914, American importers brought in Belgian shotguns literally by the ton, and even some big name American makers used Belgian barrels.
Some Belgian guns were of excellent quality, but most were somewhat short of that, being made to sell for $20 or less when a good quality gun would run 3-5 times that. Mostly they were adequate at that time for hunting, but most seen today are worn out and even dangerous.
Laminated steel is sometimes confused with Damascus, but there is a difference. The problem at the time was that barrel makers had not been able to drill a long straight hole in solid steel, so barrels were made by either twisting thin rods of iron and steel together, heating and hammer welding the result into a larger bar, then heating that bar, wrapping it around a mandrel and again heating and welding the bars together, in a spiral pattern that looked like a barber pole. The result, called Damascus, was often very attractive, but all those joints made it weak and corrosion and rust over the years have made those barrels even weaker.
Laminated steel barrels were made in a similar way, except that instead of bars, they used strips of steel, heating them white hot, wrapping them around the barrel, and welding them together the same way as Damascus.
I strongly recommend that any gun with Damascus or Laminated steel barrels not be fired, and certainly not fired with modern smokeless powder loads.
