The 058 4qt. oblong casserole with walnut serving tray. The largest of four sizes made. Other rare, non-regular production examples include scroll on sage green, white snowflake on turquoise, white "compass" on turquoise and Early American on an unusual divided version of the smallest 033 1-1/2 quart.
I have a divided 033 in the white scroll on green sage. Have you seen one before?
