Not sure why the bulb sitting crooked but it’s not the lamp socket. It’s the bulb. 12 1/2 inches tall by 6 1/4 inches wide. In good working order with a good cord has an offer on switch on the side. The socket does have some threads which makes me believe that there could’ve been something that screwed on over the bulb or maybe it just held a chimney kind of an antique gold color shipping will be $12.
