Identify this hood circa 1928-1930

This hood has a crease very similar to 1929 Buick, but the crease gets shallower toward the rear, and the area surrounding the side louvers is raised, which is not on the Buick. Another unusual feature is there is no seam at the front / rear edges- usually the sheetmetal on a hood is folded 1/4 inch along the sheared edges to add stiffness and reduce paint chipping.
