Vintage 1960's 1970's Swag Hanging Lamp Light

Vintage 1960's 1970's Swag Hanging Lamp Light. Not sure exactly when this lamp was made but it is a vintage swag / hanging light fixture. It has a 3-way socket in the upper part of the light that allows you to choose between low, medium or high.

The lower portion is just on/off. You can have both upper and lower portions on for maximum light or just turn on the lower portion for a softer night light effect.
