Other versions: This 1950s Cosack crowfoot desk lamp exists in several colours and sizes. Many different lampshades were used. Also a smaller version exists, you can find an example over here.

Louis Kalff

These lamps are often attributed to Dutch designer Louis Kalff, but Louis Kalff never designed lamps for the German Cosack company. Furthermore, Philips, the company Louis Kalff worked for in The Netherlands, never produced lamps with a crowfoot base. You will never find a crowfoot lamp in a Philips catalogue.

The Idman Oy company from Finland also produced a lamp with a crowfoot with a slightly different crowfoot base. It is also often attributed to Cosack or Louis Kalff. You can find it over here in the 1958 catalogue. The Swedish Ewå also produced lamps with a similar crowfoot base. Probably also some other companies.

Cosack Leuchten

The Gebrüder Cosack (Gecos) company was founded in 1848 as a metal processing plant in Neheim-Hüsten, Germany by Egon, Friedrich and Theodor Cosack together with Gottliebe Tappe. It was named Metallwarenfabrik Tapp + Cosack. In the beginning they made liturgical items, crosses and upholstery nails made of brass and they also produced kerosene lamps. Later the company came to the production of electric lamps.

After the Second World War Cosack pursued a modern direction. A best seller were copper lighting for restaurants. It is said that the company was declared bankrupt in 1984, but the last catalogue I have (1989 -1990) was published in 1989.

Best known designers: Gottfried Stürzenhofecker, K. H. Kinsky, Hans Wilfried Hegger, Hans-Joachim Groth, Burkhard Panteleit, Joachim O. Becker, Prof. Friedrich Becker, Waldemar Rothe and Jan Armgardt.

Gebrüder Cosack (Gecos) received 15 iF Design Awards.

Erwi

This lamp has a cast iron base made by Erwi model number YF67. Erwi was a cast iron producer, not a lamp producer. The company made cast iron counterweights for several lighting companies. Erwi produced many items in cast iron, for instance also Christmas tree stands. In all probability a German company. The company no longer exists.

At least Kaiser Leuchten and Cosack Leuchten, both from Germany, used cast iron from Erwi for their lamps.
