Yes. Some with a Setter Dog, some with a Pointer Dog and some with a dog from a picture sent in. Gold S inlay in the top tang instead of the engraved word SAFE, silver duck or quail inlay on rib, gold plated trigger and selector, "Made Expressly for ...." on right barrel, on and on.
The earliest gun like this I've found a card for was ordered by Seattle lumberman A.S. Kerry --

I'm guessing Joshua Green --

saw Kerry's gun and ordered ones for himself, and four of his friends, then ordered one for his son and a bit later ones for four more of his friends.
About half of them were ordered with maple stocks, several specified best quality walnut for stock and tip, and Anton Rez, the stained glass artist, specified best European Walnut for his.
