The Powder is 4 7/8" wide at the mouth. It is 1 5/8" tall w/o lid and 4" with lid.
The image shown above is a marriage. No tray was shown in the Imperial catalog page or listed as part of the set. The tray is not Imperial Candlewick and has been variously attributed to Czechoslovakia manufacture or Paden City, but there's no reliable documentation for either at this time.
