No Glass maker, nothing on bottom. lower heel in back is some very very very small slight lumps about impossible to make out but almost look like 11 4 3 or 1? 4 3 but way too small to decipher for sure. Leon.
Now I need to find the Exposition Quart from Delray to go with this American Quart. I know someone who has one but he reminds me of that Actor Charlston Heston when he said you can pry it from my cold dead hands. Leon.
Friend of mine, said he spent many hours doing the embossing highlighting. Did it 20 or 30 years ago when he was younger. now in his 80's sez he's not sure he could still do a good job with shacky hands & all now. Leon.
After 10 Years of trying to obtain this Bottle I finally acquired it. wasn't a easy task. I once dug a broken busted up Quart version in about 10 pieces & only half there. Been wanting a whole one ever since. As far as I know this is the only one known to exist in quart size. Gotta be others out...
