This exact style of red metal toleware tray based on the label style, specific script, and the tray design was manufactured between 1945 and 1955. The sticker confirms the manufacturer is Nashco Products (E.T. Nash Co.) out of New York. Even though the top half is worn away, the distinct oval shape, silver foil backing, and bold black lettering reading "NEW YORK" perfectly match the official mid-century Nashco label. Right above "NEW YORK," you can faintly see the letters "N.Y. 3,". This indicates New York Postal Zone 3. Because the Post Office replaced these single/double-digit zone numbers with the 5-digit ZIP code system in July 1963, this tray was definitively made before that change.
