Mid 20th century vintage meat tray, silver plate over copper, very likely a reproduction of a Victorian era antique, we think. The mark is Lifetime Brand Silver Plate.
This measures about 22" over the handles, 18 1/2" long over the tray, 14" wide across the tray. It's a little worn and spotted, copper showing through in some areas near the dripping wells. We haven't properly polished it but wiped it up a little for you to better see the wear on this piece.
