This candlestick looks just like the one pictured in Felt & Stoers' "Glass Candlestick Book Volume 3" as MO-7. It states the color was white with blue trim, but this one is just white.
Tom Felt said about this candlestick that "it is certainly possible these were made in all white. The Morgantown Glass Museum has some pieces on display in all white."
The candlestick is shown in a Morgantown advertisement.
