Bought a couple interesting weights on eBay recently simply because they were a little different.
The triangle of this "domed triangle" shape is a little off, with sides of roughly 2 1/8" x 2 1/2" x 2 5/8", and a height of about 1 1/4". From the little I've learned about glass work, I'd imagine this shape had to be "eyeballed" as opposed to, say, a spherical, ovid, domed, or other circle-based weight that's rolled to and fro being evenly shaped with a wooden block.
The clear glass is exceptionally clear and completely "incidental bubble"-free (the specs on the photos are dust, not artifact in the weight) and has a slight blue color to it. The inner stained-glass looking colored portion is not solid, rather it's like a very thin "wall" -- transparent except for the few red-colored portion.
The base reads either "LT '94" or "VT '94".
This next one is an eyecatcher. It has two recesses, almost opposite each other, with placed air pockets giving it the raptor-ish appearance of something with two eyes. There are many very tiny incidental bubble in the glass -- so small I didn't notice them until they appeared in the photos and I went back and took a closer look at the weight. The sig around the base look like an "L" (but could arguably be an "h" or "R" also) first initial, followed by a last name that looks like "Ja??tt". If you squint just right, the first letter in the last name might be an "S". The third letter in the last name has barely visible little hitch or stutter at the top as if it might be a lowercase script "r".
