Question: When were clear, sculptured flame bulbs of the type attached here first produced? They appear in the Sears catalog by 1937, with only 25 watts, and by 1951, with 40 watts, but I want to know when the clear version were first manufactured. I'm trying to verify if they existed in 1926; I know shaded flame bulbs of this shape in amber or ivory were around then but I need to know about the clear version. Thanks.
