Any info on this unusual looking Pureoxia?

Oops, sorry for the mystery. Big muddy river that winds 80 miles through many Massachusetts towns before dumping out in the Boston Harbor. I’ve always hunted for bottles at 4 specific spots but I’m starting to realize it would be harder to find a spot on the Charles without bottles. I grabbed this one in Needham.
