Worth point help - Napier Sugar/creamer

https://www.worthpoint.com/worthopedia/napier-duplex-cream-sugar-server-419377358

I've seen ebay solds as low as $10, and an auction sale record for $750. I went to a church rummage today and found two sets sitting there, marked Napier Pat. Pend. Another search popped this same set up in the Rhode Island School of Design as being designed in 1935. My guess is they were popular and had a longish production life.

They turned up with some little dishes, butter pats maybe, and serving utensils that are also marked Napier. News to me - who knew Napier made tablewear?

 

$99.99 (2013)

 

Thanks. I'm in for about zero. (LOL) There were two of them sitting on a smallish tray. The tray is half a pound of sterling, and it was still there an hour into the sale. Everyone saw the Napier on top and thought the tray was more of the same.
