Hi, I am looking for the following information on the jenny Lind locomotive. I have a model in very unused condition and on first look I found that the driving wheels are just spinning freely with no movement of the motion at all. So first question is does anyone know how these wheels locked onto the axle, I can’t see any key ways or pins. And second question, as anyone a set of plans showing the motion and also the plumbing of the loco. Any help would be appreciated. Thanks
