This is starting to frustrate me. It's a b16a head. It's not hollow, very solid and has some weight to it for being so small.
I've never seen it before in all of my times playing with the head or just flopping it around to look at it. At the same time, there's nothing in the house that the piece would belong to. I want to just drop it but at the same time, I'll be paranoid if I don't know what it is. I should just take it to a machine shop and see if they know..
