Back in the 1980s, a series of Snow White and Dwarf frosted glass figurines were manufactured, probably in Italy. But these figures typically came with painted highlights. This Dopey appeared to be unique because it had none.
I found a Snow White piece featured in the 2007 Hake's Price Guide to Disney Collectibles. It shows the painted highlights seen in the other figurines in this series. But then not long after, I came across online an unpainted variation too.
Here she is with six of the seven dwarfs.

Doc clocks in at about the same height with similar highlights...
