This is a very unusual frame, done from a photo of a frame from 1920s-30s. Gilt with metal leaf and polychrome panels. The ornamentation is poured Bondo, oops, CPR. See the previous post. Regular Bondo with the addition of liquid fiberglass resin, is "pourable" but mostly non-flowing. It will gel, and stay in position. I've used this kind of poured ornament on several frames as an alternative to conventional ornaments.
This is the image I was e-mailed, to work from. I'm not sure what the material used for the poured ornament is on the original, probably a gesso with oil added.
