This is a 10" model with green and red Christmas Holiday highlights. L.J. Houze Convex Glass Company was formed in 1914 by Leon J Houze. Houzex Glass for short. Works great. The hole in the shade is for heat to escape. Some think this is for the addition of a finial, however this is incorrect. The nickel chrome connector shows very tiny surface rust and the hole in the shade shows some damage, otherwise it is in great condition.
