This used to be a decent place to post and get a reply, but not sure if anyone is around to help anymore.
My first impression is this one may not be worth the trouble. The ball is dingy looking and the auto is not on the sweet spot where most people want it. It's pretty much a scribble job and we don't know if it's even on a OML ball. Unless you have some clues to go by it might be a lost cause.
