Hi Dirk,
Thanks for your reponse to my post. It was most helpful. I did a search as you suggested and discovered that my bowl was originally a McKee Fentec mold (circa 1906). Jeanette, who took over McKee in 1961, later produced this bowl but with three feet (footed). I will do more research, but if anyone else cares to add to the thread it would be greatly appreciated.
Thanks, again, Dirk!
