Here you go Miser. I didn't intend to ignore your questions. The marble is about 7/8" at the largest and out of round by about 3/32". There are lots of bubbles in a kinda cloudy green glass. I have seen some of the marbles intended for fiberglass production. This doesn't look like the ones of those that I've seen. After looking at the "pontil variations" page at the Akron marbles site, I thought it might be a hand made puree with a strange melted pontil or something, but I'm pretty much over that. lol. Here are a couple of other pics.
And Dan, thanks to you for the pics too.
