Roy's lamp is a Model B proudly sitting on top of a Washington Drape font. The Model B was one of the best burners Aladdin made and you can still get replacement parts for it. My oldest lamp is a Model 12 made in the late 1920's that was my Grandfather's lamp. Just like straight razors and old cast iron skillets, collecting and using these things is addictive. Hmmmmmm, maybe I should try shaving by the light of my Aladdin? :)
