Sadly doesn't fit 4 out of 4 Aladdin lamps I own.
"This is a perfectly good brass cap at a reasonable price, however it did NOT fit my model B era Antique Aladdin font (base). My other two lamps (one is an old footed Lincoln Drape, and the other is a modern ugly mirror brass hanging lamp) both use a male type cap with outside threads. So this fits zero out of 4 Aladdin lamps. I guess I am going to have to pay the crazy $11 for the 3 cents of brass for the brand name cap! Sigh."
