In 1856, John Nevill and Lemuel Curtis recieved a patent for simplified damascus substitute [alloy] assigned to J P Farrar of the "Damascus Steel Manufacturing Company"...kind of early for the golden age of double shotgun production, but none the less, another lead.
The Sachs technique or something similar has been seen on a high grade Parker
There are several more damascus shotgun patents to be shown in the next weeks...sorry they're difficult to locate because they are pre- personal computer files...

Interesting description for 1,167,233. He was trying to fix the problem of corrosion caused by early nitro powder. His solution was to leave the mandrel in the damascus tube then bore out the mandrel. This gets referenced years later by E.R. Shaw for a patent they filed regarding barrel inserts.
