Waterman's Barrel Ink Bottle.

In another post I showed three Waterman's ink bottles that are more recent than this one.  This is a 2 oz. bottle for no. 6 ink.

Waterman's Pen Company was founded by Lewis Edson Waterman in New York City in 1884.

Of course the bottles changed over the years, but bottles of basically the same shape as those shown are still sold today.

An old barrel shaped Waterman's ink bottle is shown in another post on this site.
