Rare giso hanging lamp model 4c designed by w.h. Gispen for gispen in 1931. A greater length was possible at an additional cost, as with these lamps. Dimensions: h x d = 190 x 30 cm. The pendants (160 cm) can be shortened on request (see photos). The neck opening of the sphere is 15 cm. Material: metal, bronzed and glass. One of the chalices is marked with the gispen brand: giso marque déposée. These lamps are still in very good condition, normal traces of use and wear (see photos). Source: gispen tubular furniture and lighting 1920-1940 and gispen lamp catalogue (1931) no. 29, page 8. What makes it even more special is that we have five of these lamps (the price is per piece). Very nice to decorate a 1930s house / building, for example in a corridor or stairwell. This piece has an attribution mark, i am sure that it is completely authentic and take full responsibility for any authenticity issues arising from misattribution, up to 250v (europe/uk standard).the wiring of this item may be original and might need replacement, if not specified otherwise.
