From your description it has to be 1909-1912. If it has a small fill it's 1909-1911. The slotted cone burner changed to the rising-cone in 1913. The early 1912 still has the large air chamber surrounding the burner gallery and the later 1912 starts the domed chamber with winglock cone. I'd love to see some pictures.
