Thanks Nick, I looked thru the reference you provided and did find an Aerolux bulb that came very close to the one my friend has. There is one in the 1970-1974 catalog that is very similiar with the flowers, leaves and heart. His has the same pattern except without the heart. I don't like to assume, but after looking at so many bulbs am gonna assume that this is the company and the approximate year it was made. The bulb does work and provides a nice glow tho I feel it is on its last leg as the illumination is not very bright any more. Thanks again, and hoping you have a nice day!!!
