The RF-16 should have 2 vertical panels of screening on the fireman's side of the engine. The Bachmann model does not have this. To simulate the screening, I used the Model Memories decals for the NH EP-5 motors. There are decals in the set for the intake screens that were located on the sides of the EP-5 carbody. They worked perfectly! I used them on the D&H model.
Model Memories decals is an outfit I don't know, will have to look them up!
