Another one of these lamp bases, unusual colourway of green and pink/purple (unfortunately without light fitting; funnily, I run across these topless lamps from time to time -- one would think that it was more likely to find the metal part without the glass

)
A while ago I saw a very nice blue one.
According to the bohemianglass.org website these were made by Ernst Steinwald glassworks (Franz Tomschick from 1938) for Glasmanufaktur Karl Picking Dresden.
