Prewar ballooner badges came in two sizes, 2 3/4"? and 3 3/16" I believe. You can really pick up any prewar brass large badge unless the badging is written along the downtube. Packard, Lincoln, Pullman, Electric, and on and on.

Not to drag syntax into this, but I don't think that's technically a double diamond. It looks like your seat stays have a curve (unless the image is deceiving), when the double diamond were straight. Nice C-model, though, 36-37?

Did they ever make a C model "Double Diamond" frame?
