Dark Red Burke and James Darkroom Light Cover Very Vintage

Description

This is a very vintage Burke and James darkroom light cover. It is a dark red and heavy glass. It has an aluminum base. The hole in the base is for screwing onto a light fixture, then the red glass dome screws onto the base effectively creating a dim red light that will not affect photographic negatives during development.  5 1/2" tall including the base and the base is 4 1/4" wide.  It is in excellent condition.  There is a manufacturing flaw in the glass from an air bubble.  See all photos.
