I have a vintage lamp that I inherited from my father, who inherited it from his parents. (See the attached images, one of which has the dimensions.) According to my father, it was originally a table lamp and my grandfather made an iron extension to turn it into a floor lamp. According to my, my grandfather received from one of his employers, Mr. Charles Templeton Crocker or Mrs. Helene Irwin Crocker Fagan. (My grandfather was their chauffeur.) Helene Crocker divorced Charles Crocker in 1928, then married Paul I. Fagan a few months latter. They honeymooned in Europe, so it's possible that the lamp was acquired then. On the other hand, Mrs. Crocker may have received it as a wedding gift for her first marriage (1911). The base of the lamp seems to be marble. The pedestal appears to be bronze. The urn is soapstone or alabaster. (I'm thinking it's alabaster.) The cap and light assembly are brass. The cap is held on to the urn by two brass threaded knobs. (See one of the attached images for details of the brass cap.) Besides the light assembly to which a shade is attached, there is a light inside the urn, so that when the light is turned on the urn is illuminated. There are three (bronze?) reliefs on the urn that appear to be busts of Haydn, Beethoven, and Mozart (L-R, according to full image I've provided). I have done some research, but have not been able to find any information specific to the lamp. My wife did find photographs of the Beethoven-Haydn-Mozart Memorial, in Tiergarten, Berlin, Germany. The images have caused me to wonder if the lamp is German or Viennese in origin. I'm also wondering if the three figures forming the pedestal of the lamp depict the three Muses of Greek mythology. My purpose for seeking information about the lamp is that I'd like to restore it to being a table lamp (presuming it was originally a table lamp). In order to do so, I need to know what the column supporting the external light assembly was. I also would like to know what would be an appropriate shade to go with the lamp.
Any help would be greatly appreciated.
