Trays measure 7 and 10 inches across.
The pattern is known as Chunky or English Hob and Button (pattern #2266). The glass won't be lead crystal. The stand may be silver plated and was probably made in the US See: http://www.bellmarksheffieldsilver.com/home.html
The Chunky pattern had a long life from the 1920s through to the 1950s, possibly beyond, in clear, blue, green (including uranium), pink and amber.
