The scale is impressive. The top width is 20-inches. The shade is almost 14-inches wide. The height is 10-inches.
The shade sits in a metal ring, which is attached by two clips to the upper housing. The clips have short chains which prevent them from accidentally opening. Cool.
The upper housing is surrounded by distinctive holes to help with ventilation. The bottom of the glass shade also has a hole to aid with ventilation.
There are three sockets, each accepting a 100W bulb.
Well, now I have to go watch a 1951 movie classic…
