My great grandfather was a salesman for Hanovia products. I have working Hanovia Luxor model floor fixture that was manufactured in the 1910's. The wheeled fixture weighs perhaps 70 pounds. It has a semi spherical aluminium reflector that can be raised and lowered. The mercury quartz lamp appears to be the same as the one shown on this site under Discharge: MS special mercury (MS0001). The URL for the image is:

The fixture is located in Ledyard, Connecticut.
