Correction was requested, so given. That US Navy button's body is solid 1-piece brass, so it cannot be the Albert-book's button NA-108. The closest match I can find in the button-book by Albert among the 1-piece brass US Navy buttons is button NA-86, showing an eagle standing atop a vertical anchor inside a rope-bordered oval. NA-87 is very similar but 87's anchor has no rope. Based on the time-period of the backmarks found on varieties of NA-86, it dates from approximately 1825 through 1830, and was manufactured in Britain.

It is what we button collectors call a button's "backmark." Button manufacturers sometimes put their business name and location on the button's back, as a form of advertising. Also, some manufacturers gave their customers the option of having the customer's business-name and location on the back of the buttons he purchased. For example, a clothing maker (tailor) or clothing store owner would order hundreds of buttons with his business name on the back from the button maker. On your button, "Alexander" is the name of a clothing dealer, and "Norfolk Va" is the location of his store.
Judging by the spacing of the letters and blank spots in this button's backmark, I do not think there is enough space for the word after Alexander to have six characters, such as Newark. I think the "ark" could be part of the 5-letters last-name of the business owner whose store was located in Norfolk Va. "Alexander --ark Norfolk Va." Or perhaps the backmark is two men's last-names, such as "Alexander & Park".
Also, it seems strange that there would be two city-names (Newark, Norfolk) without an "&" between them in the backmark.
