This illustration came off Towbars & Trailers website they still carry spares for quite a lot of rod brake components.
Western Towing have illustrations of the different sized pre auto reverse brakes. There are slight variations.
The links can all be found by entering Lockheed trailer brakes into a search on Google images.
