One you don’t see everyday, and one that I have owned for quite a few years… here is a large round master ink bottle with lobed shoulders, embossed “E. WATER’S / TROY, N.Y.”. Applied top and iron pontil base. This one is a beautiful citron green color, and has super glass character! There is a tiny divot on the lip edge… not sure if it in-manufacture or not, but I have included a close up picture.
