Identifing an artifact

Hello everyone, My name is Stephanie Desjardins and I am currently a second year student in the Applied Museum Studies program at Algonquin college. Terry Quinlan assigned me a silver artifact for my conservation class and I am uncertain as to what it is. The institution labeled it as an 'egg tray' but it doesn't fit the characteristic of an egg tray or frame. I have also done more outside research but doesn't seem to fit any of the descriptions of objects I thought it could be. The artifact is electroplated silver. It is mainly a dish in the shape of a croissant with two circular shapes found on the back which are held up with two support beams. And a handle is found on the base of the dish that connects with the circles. Sorry for the short description. I can't seem to upload a picture or copy and paste one in of the artifact. If you have any idea of what this artifact is, could you kindly email me at desj0236@algonquinlive.com as well as provide scholarly sources to confirm your identification. Thanks, Stephanie
