I have a gear box on the way for my 101.07403 which is going to come with a broken and incomplete right handle lever. Some preliminary searching has found at least one home machined copy for part 10-1586. I'm not afraid of that as a project. Would anyone happen to have even a preliminary sketch of the casting that I could use to machine out a part?
