The most common size of the American Standard Ink bottles found around here is the quart size (there was no gallon bottle).
I read that the company had contracts with the New York school system. They bought the ink in the most economical size.
THANKS for the responses guys. It is starting to sink in slowly. Really trying to stay even keeled about it, I know I'm not likely to ever dig anything quite like this again, so I just say a big yahoo - and head back out and dig and dive and enjoy it as always (rather than try to hope for another Harrisons type find)
Went out a total of 4 times to this spot. There is a lot of new stuff, mostly screw top Fed Law Prohibits flasks, and newer beers and sodas. I got a couple of good ones though, one on the third dive and one of the fourth This ones a nice Rushs bitters
