This is a quality UK made wire frame for making a soft bodied lampshade.
Base diameter  22” 
Slope height 14”
Top diameter 14”
It has a top ring fixing suitable for an American harp floor lamp or large table lamp.
Note that this is a vintage but unused frame and there are grey marks/scuffs etc so it would benefit from a light re- spray
Pay just one P&P no matter how many frames you buy!!
