Family Heirloom Lamp....

I have this old family heirloom lamp circa 1920 ish...
Don't know anything about it, but would love to find out anything
someone could share with me. what it is called, era, possible maker ?? It is about 6 ft tall and has small claw feet. It does not have a shade, so would love to know what kind it would take and where I possibly could find one. I've never had it appraised, but also would like to know ballpark what the worth may be... I want to keep it in the family, so would love to find shade .
Any info will be much appreciated!!
