The Wilcox Silver Plate Co Tea Pot in the Du Barry design is a stunning example of Victorian-era silverplate craftsmanship. Made in the United States between 1900-1940, this tea pot features intricate hand chasing and a classic Du Barry pattern. With its elegant design and historical significance, this tea pot is a valuable addition to any antique or silver collection.

The item is a piece of silverplate manufactured by the Wilcox Silver Plate Co., which later became part of the International Silver Company.

Here's a breakdown of the markings and what they mean:

WILCOX: This identifies the original manufacturer, the Wilcox Silver Plate Co., established in Meriden, Connecticut, in 1867 (originally Wilcox Britannia Co. in 1865).

INTERNATIONAL SILVER CO.: Wilcox Silver Plate Co. was acquired by the International Silver Company in 1898, but the Wilcox brand and designs continued to be produced under the International Silver Co. umbrella.

Quadruple Plate: This marking indicates a higher quality of silver plating, meaning the base metal (often nickel or copper) was coated with four layers of pure silver during the electroplating process, theoretically making it more durable than standard silverplate.

7901: This is likely a pattern or model number used by the manufacturer to identify specific designs or pieces, such as a tea pot in the "Du Barry" pattern as indicated in search results.

In summary: You possess a vintage or antique silver-plated item from the Wilcox Silver Plate Co., manufactured after its acquisition by International Silver Co. in 1898. The "Quadruple Plate" mark signifies a higher quality plating, and "7901" refers to the specific pattern or piece within their catalog.
