Does anyone have any decent knowledge of the historical timeline of the Black Squiggle? I have one at home (pics to come later) and the base is what Lamphead referred to as a "tall" (http://oozinggoo.ning.com/photo/aristocrat-base-that-garnered-a-sid...).
Previous to acquiring the lamp I knew of two other variations - your standard Aristocrat geometry with symmetrical lower and upper cones on the base; then the same, but with starlight holes.
I think black squiggles were last made in 69 or 70. I guess I can safely say 70, because in 69, the "tall" base may not have appeared yet (can't confirm). Both tall bases and squiggles were definitely gone by 72, when the short-lived Commander appeared (matte black Aristocrat, short base).
