This version was made during the 60s and I don't know when this was stopped being made .This should have Two 2FT 40W MCFA/U metal strip Fluorescent Tubes ,but one of them is missing. The bowl is missing from this lantern  and the bowl was white in colour. These photos was taken in Dec 2005. I seen this light in the summer 2007 .
