Hi Will,

Welcome to the Forum.

I suspect this is 'Nickel Plated Nickel Silver'. Nickel silver usually contains around 20% nickel, the rest being copper and zinc, and a plating of pure nickel may have been applied to achieve a preferred finish to the item.

A tidbit on nickle plate I ran across...In 1906, a polishing paste called "Argentine" was noted as being demonstrated at R.H. Macy's in New York. Said to contain real silver particles, it was recommended as the only proper product for polishing nickle plated so and so (my words). BTW, N.P. was used in a variety of traveller's carry-alongs such as collapsible drinking cups.
