These beauties were manufactured by Hanau GmbH in the 30s and 40s after they started the production of quartz lamps in Hanau, Germany during the early 20th century. The design is absolutely mind-blowing. Basically the whole fixture is made out of brass and copper parts almost for the last bit by paying extra attention to the smallest detalis. It has been converted to E27 bulb holder. This particular piece is from an early series, numbered and signed, totally one of a kind.
