I have a curved tray with grape leaves signed on back looks like Bruce Cox and stamped 362.
In trying to research I found an article with this information:

“Aluminum is a highly-functional material that is ideal for serving food right from the oven or refrigerator. The high-quality, pure aluminum alloy used by Bruce Fox is perfectly safe for food items.
Bruce Fox founded his company in 1938, as a young, talented sculptor, eager to explore his “new-found” knowledge of metal-smithing. Some more interesting history about Bruce Fox :
Before founding the company in New Albany , Indiana in 1938, Bruce Fox was a studio artist in New York City . During its height in the 1940’s and 1950’s, aluminum was a relatively rare, “space age” product that was new to many people and had great appeal as a decorative element in people’s homes. Following Bruce Fox ‘s passing in 1960, the company sold the gift ware line to Wilton Armetale in 1975. Wilton continued to produce many of the popular designs from the original Bruce Fox molds for many years thereafter”

However I am finding on this site and others pieces that are signed Bruce Fox
Needing to know if it is Fox or Cox May make a difference or it could be a totally different signature.
Thanks for any direction.
