This urn was originally identified as Westmoreland but the color created some questions and a board member contacted Lorraine Kovar requesting verification and received the following response.
...the urn was a Westmoreland 1943 mold that Fenton had. I think they called this Steigel blue opalescent. I also have a Sawtooth piece in this color. They also did the urn in pink carnival which I have. ..... Lorraine Kovar
Beginning in 1983, the "Script F" appears in moulds acquired by McKee or other glass companies (Verlys, Paden City and U.S. Glass are exceptions). An "8" to denate the 1980s or a "9" to denote the 1990s may also appear. The "0" is used from 2000-2009. This urn has an almost unidentifiable (due to size) script "F" with an 8 on it.
