I am looking for help on a five car set of Welz Amfleet cars I recently acquired. If you look at the attached photos, the ends of each car are somewhat warped - they do not look the way they should. In doing some research I believe these were originally Williams cars that Mr. Welz custom painted - but I am not sure. Can anyone confirm this and possibly point me in the right direction as to where I might possibly find replacement ends? Thank you for any help!
