The bell stem version of the Washington drape table lamp was only available for a single year.
One thing interesting about this version is that it is the only lamp in 1941 production that does not appear in the 1941 dealers wholesale price list. Sales seems to have been limited or only started after the price list was printed. Either way this model is harder to find and less documented than other single year lamps.
These lamps were available in clear, green and amber.
