Perhaps Durgin's most elaborately decorated pattern, Regent not only has elaborate shell and scroll work in it's design, but varied pierced work in three spots on the handle, and down both sides of the bowl.  Additionally, there is a swag and flowering branch engraved in the bowl and also around the monogram in the cartouche.

This spoon has a nice script triple monogram, perhaps MBC

On the back it is stamped with Durgin's D hallmark, sterling (somewhat faded), and the the Tilden-Thurber Co.
