The Laurel and Hardy of Bagley Carnival uranium glass butter dishes. Laurel is marked with the registration number 849118 and has a much lower, less ridged lid, a smooth knob and less glass in the base section. Hardy has no mark, a high deeply ridged lid with a wider exterior lip, a ridged knob and more glass. The shades of green also appear slightly different, with Laurel being slightly more blue. All other dimensions are the same. Laurel is the one shown in Angela's book as being in the 1953 catalogue. I assume that Hardy is the older of the two. Has anyone noticed any other variations in Carnival? My two cheese dishes, one marked and one unmarked, only have a slight shade variation
