White glass opaline ball globe 20 cm

White glass globe for ceiling light from the 50s or 60s. It is sold without the support, to replace a broken globe but it can also be diverted into a table lamp by making a support (in turned wood for example). It is in good condition, no cracks or chips, just two or three small stains or light colorings which seem to me in the glass. It measures 20 cm in diameter, the opening (which is used to hold it on the support) measures 10 cm in diameter (then narrows to 8 cm) for a "height" of 1.5 cm.
