This is a great fixture from the German company, Staff Leuchten. The bubble glass was featured in many of their styles and was produced from the 1960s until the 80s. This is the largest version available at 19.5" in diameter. Based on the stamped mark it is an earlier version. It can be mounted as a ceiling mount or as a wall sconce. It has 3 medium base, E26, sockets. The wiring is in good condition and has been checked by a professional. The mounting plate is 11" in diameter and the glass threads on. The glass is in great shape with some minor paint loss on the back. The mounting plates have been painted black and could be stripped to the original if desired.
