There is one other bit of information I have on the Whiting Engravings:
Back of a Whiting Hand-Hammered tablespoon 5-3/4 inches long with smooth bowl (these hand-hammered "vine trailing" spoons are quite uncommon):
And the front of the handle:
The engraving on the back of the handle, the "1881" date engraving, was so unbelievably similar to a cheese-scoop which is owned by a prominent silver dealer, and this cheese-scoop has a hand-hammered handle with a similar vine-type of plant trailing up the handle, and there is a mouse at the very top of the handle, and on the back is says "ELIZABETH CHURCHYARD" in the exact same font as my spoon. When I asked the dealer, who seemed quite knowledgable, he said that in his opinion, both the name and the date were engraved by Whiting In-House. Note that there is a monogram on my spoon, which is cruder and much different in construction, and that monogram must have been done at the retail-shop level, or else purchased at a retail shop and then taken to a local jeweler for engraving (my opinion).
This might add some new facts to the Whiting Engraving Paper.
