L.J. Houze Convex Glass Company was formed in 1914 by Leon J Houze. Houzex Glass for short. This model is a 10" model with black highlights. 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 some surface rust and the hole in the shade shows some imperfections or very minor damage, otherwise it is in great condition.
