I call this the "fish bowl" because it has the characterists of a fish. It is turquois, white and gold in color. I can not identify the maker by the signature.
I found this item at an antique store in Milledgeville, GA. It still has the instruction manual with it. There is also a letter in the drawer to a farmer in Durham, NC dated 1943 form the Department of Agriculture. It also has a metal case in one of the drawers with items for the machine in it. It also has original thread and needles inside.More photos available upon request.
The Chalice has an etched rim of some kind of flower and leaf pattern. The base has 6 lines/circles around it. It has no scratches and doesn't appear to have ever been used. The bottom is marked Tiffany & co makers 13171 18 Kt. gold and has an m at the bottom that looks like a greek letter. Above the stamp is a small number 601 that looks like it was etched into the gold by hand. It is a very reflective yellow gold.
