No published history on the company.
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.

Your gun was made by the Dumoulin firm in Belgium between 1885 and 1905. Value will be under $250.
Yes
Most likely was imported from Belgium c. 1900-1910. "Nitro" refers to smokeless powder, so it would have been made after 1900. Damascus barrels would place it before WWI.
Possible.
Wilmot Gun Co was a trade name sold in the US, but the actual manufacturer was Henri Pieper or Anciens Etablissments Pieper(1877-1957) in Belgium. With damascus barrels and external hammers, the gun was probably made c 1885-1900.
Crown shotguns were manufactured in Belgium. I have read that some of them had Damascus steel barrels, so DO NOT fire modern shotgun ammunition in it.
