I'm thinking pie bird also. It's an unusual form though. The hole in the top could be for some sort of bud vase but I doubt it.[] Kinda looks like a duck onna nest, and I believe your correct a pie steam release device........

I see spark plug was mentioned.It does look like that as well.But I've never seen one with a aluminum bottom like that.All the old ones I find never have much left being made of iron.Looks like aluminum would melt screwed in the head of a engine.Also looks like it would strip out easy.Below is how mine always come out looking of that age.
