I have this as the Krupup Parasol. Built and flown in 1927 around New York. (Also, the Gentleman in the photo might be of American Indian ancestry which is interesting). I have a newspaper source and recall a one sentence mention in a period aviation journal some time ago.
This could very well be a kit built Heath Parasol that was just different enough to have a new designation. That said, I'm not 100% sure about any of it so going open board.
