Sorry for the dark image...After viewing the examples in Martina's Vintage Lava Lamp Gallery, I believe it to be an Aristocrat(?). The date on the felt, under the base is September 01, 1969. Overall 16.5 inches tall, 5.5 wide base, on bottom where it contacts the table. The globe, by itself, measures 11.5 inches tall, and looks like 5 inches at it widest point. The lower cone on the base has the holes in it for the "starlight" effect. If anyone has a guess on the size (how many oz.), I would be grateful.
As you can see, the screw on cap is broken, and cracked, and severely brittle. The fluid level in the globe is low. I believe I can fix that, but my real question is "Where can I go to get a new, or used cap??? The cap has a 2 inch diameter on top, I am guessing at 2.5 at the base, and is 1 7/16 inch tall. It screws directly to the globe, no bottle cap underneath.
