This WV 339 flush mount was designed by Prof. Wilhelm Wagenfeld for Lindner Leuchten in Bamberg, Germany in the 1950's. It has a white opaline glass diffuser on a white porcelain ceiling mount and socket. The secured rubber ring makes this lamp water- and dustproof. These lamps were also sold by Raak and Philips. See the picture from the Raak catalogue of 1957 (model B 1078). We have 3 of these lamps and also 4 in a smaller size of ø25 cm available. All lamps are in a very good condition with minor signs of age and use.
