One of my glass books calls this number 400/68D Imperial Candlewick serving piece a Party Tray, others call it a Pastry tray. It has a heart shape center handle and measures 11-3/4 inches diameter. There are no nicks, flakes, or chips and the glass is crystal clear. When held up to the light you can see a few rub marks to the glass from use and storage, no deep or long scratches though.
