Here are some images of three of the six styles of cobalt vases that I have identified by this maker. The shorter is about 5" high and 4.5" wide. The middle size vase is 6" high x 3" wide. The tallest vase is 8" high and about 2.5" wide. The bottom chamber of the tallest vase is lighter blue, probably due to stretching of the glass.
I am fairly certain these vases are by the same maker though there are some similarities and differences between them.
Similarities: Cobalt glass, blown into a two part mold, USA on the bottom in the same font, mold number on bottom.
Differences: Bottom finish varies between different styles of vase, periods separate USA on some vases, shade of cobalt varies.
After a few years of research, no maker has been identified for these vases. I tentatively date them to the 1930s, but that is a guess.
