The amber one is from the Glass works Auction. I've been doing
alot of research on the one with the Pitkin type and it possibly could be from Hilltown Glass Works from comparisons with examples of shards of glass dug at the site. It's all speculation. You have some really nice chestnuts there.
The 16 rib Pitkin-type is great - I do not know exactly where and when they were made but they strike me as 18th century SJ types. Love to hear other folks thoughts...
I just have to say all of these flasks are absolutely amazing and WAY out of my league... it's fun for me just to see pics of them and admire.. wonderful glass, my largest congratulations to you!!!!!!!
Have either one of you ever run across any "South Jersey Pitkins" made in a 19 rib mold in a nice sea green color? We have dug shards of several of them in Burlington. Heres a picture of some shards from one early privy dating 1770s-1780s.
