Vintage 30s The Fitzgerald MFG CO.  Magic Maid Large Mixing Bowl Custard Color Glows Green.  Please see all photos as part of the description.  As I am not an expert in vintage glass.  This piece was purchased with the model D mixer however I can't say for sure if the bowls are model D.  This color is a custard soft color, glows green under a 395 UV light.  The bowls rim is in great condition, no noted cracks or chips, some staining on the inside and outside of bowl, scuff marks from use, age and shelf life, there is a solid white line all the way around the bottom area (see last photos) I can only see it on the outside not visible looking inside the bowl. Looks like a marble streak, could be a factory flaw, honestly I'm not sure.   Large Embossed MAGIC MAID on one side and FITZGERARLD ON THE OTHER.   Check out my store for the beautiful matching Reamer.
