The Sunshine kits feature a full interior. The inside face has stake holder brackets. Wire to complete the holders is provided, so that they can be placed in any position. Soft aluminium and a mandrel of the end door shape is provided so that the modeler can create a double sided, thin walled door. The simulated wood floor is independent for separate painting.
Castings are the standard gray urethane.
The kits contain all parts except trucks and couplers. Full instructions and a Prototype Data Sheet are included. The Erie diagrams state that the last block differed from the first two in application of an Ajax power hand brake, rather than the Universal used on the first two. The Universal brake was flush on the ends, but the Ajax was parallel with the sides. The trucks were simply classified as cast double truss design.
