Maybe, sort of. Most of the miniature / dollhouse pewter wares were 100 years newer than you're thinking, a lot made in Germany, most commonly tea sets... so I'd be inclined to think maybe it was a creamer or teapot if it had a spout.
The story of Aladdin has been around since the early 1700's that was why I thought it could also be the lamp although it wasn't a stand alone story it was with others in 1001 Arabian nights.
