According to Barb Chamberlain, these little lamps are 6 1/4 inches tall to the top of the chimney and the base diamater is 3 1/4 inches. The maker is unknown.
They are very rare. I have no reccords of any selling at a Carnival Glass auction.
Beware of lamps called Aladdin Lincoln Drape. While those go back to 1909 (and are still made today), none were iridized to the best of my knowledge. They are easy to spot as the have a stem making them quite a bit taller.
