So off to work I go....This lamp was at my Sister's house, and this lamp lived with my Grandparents for years-heck they might have bought it! Anyways, Grampa or someone back in the day re-wired this lamp too I think. So I cut the cord and get the thing loosened up-it's pretty tight into the heavy base.
It's an adapter! So Easy, just screw it in and TA_DA! See it in there? I got one at my local Ace Hardware store-it was about $6.
