Great input guys. I'm glad I asked. The previous owner removed the light for some reason, I expect to change the glass, and then misplaced the frame. He cut out an oval piece of 1/8" plexiglass for both inner and outer and actually did a pretty fine job, so much so that it doesn't draw the eye like you might expect. Anyway, I'll let you folks know if it fits in case the same issue comes up elsewhere. Always fun reading your input. Thanks again.
