Green Glass Frog, Old, heavy, great shape and color, Maker?

Hello All,
This is a new purchase, I have a number of these, glass and pottery frogs,....most are in the garden, but I have a couple around the house. By the wear on the bottom of this one I'd guess it's pretty old. The shape is slightly angular, possibly Art Deco vintage. It's a heavy, solid piece, 4+3/8" inches high, and about 6" inches long. I was hoping someone might know the maker. Thanks for any looks and help.
Happy Winter/Spring day to you all,
Tony.
