I've got a "junker" AS 984 I'm trying to get running just for the experience. It needed a new mainspring which I ordered. When I received it I proceeded to take the mainspring barrel out and promptly broke the screw off in the winding arbor. So now I need a mainspring arbor and screw.
So, in searching for a screw and arbor, I'm wondering how many AS models might use the same arbor and screw?

Thanks Chris, Just what I need to know.

Now to find a (another)junk movement.
