Featured New Amsterdam #264 Lidded Pitcher: Creamer, Or?

Quadruple Plate, 4" high overall, 3 5/8" base diameter, 1 3/4" rim diameter; weight is ~5.9 oz. I think it's too light for a teapot, but I'm not familiar with creamers having hinged lids. Can anyone say when this may have been made?
I was initially attracted to it for the quail-top-knot thumb grip on the lid. When acquired it had uniform exterior tarnish, as it does now, which seems not to have gotten very much darker in ~10 years; it's not black, but grey, an' the interior is bright. Thanks for lookin'!

 

If I were guessing, I'd think that was restaurant ware made in or around Manhattan circa 1890. New Amsterdam is the old name for New York City, specifically Manhattan. That's about when silverplate was hot. The totally flat base makes me think restaurant or maybe railroad. Some roads didn't mark their pieces, especially broke/cheapskate routes like the CNE. If this was O&W it would have the road name on it.

 

This page says it is an "early trademark of the Knickerbocker Silver Co."
