luv2safari,
Since you mentioned 9.3x72R, I'll tell you that my FIRST hammer gun was a 9.3x72R under the pair of 16 gauge shotgun barrels. It's bored Modified & something near to Improved Cylinder - It's PROBABLY built about 1885-90 & rather "plain Jane" in looks. The actual maker is un known & probably was a "group effort".
What I first thought was the maker's name (W. Deist) is the name of a tradesman/merchant that had his retail business in Lower Saxony from about 1875 until about 1900.
I still like "Plain Jane" very much, as for a drilling, it's quite light to carry afield & seems to point better than my other shotguns. I have several "fancy" circa 1900 combination guns that are ornately decorated but that stay home in the safe on most hunting trips.
(A German friend loaned it to me to go on a circle hunt in 1970 & I liked it so much that he sold it to me "for peanuts". - Erich loaned it to me because he didn't like the old drilling at all. = "Opinions are what cause horseraces", applies here.)
yours, tex
