Based on Al's description, it sound like the Atlas, Kadee, and Athearn offset twins are the long-taper design, while the drawing on Accurail's site would suggest the "short-taper" design.
The RPI site does include some self-confessed confusion on how to describe the taper. The RPI on-line photographs show all three of Al's configurations. It could be that Accurail may be providing the short-taper model not available previously, but only an exam of the model will provide confirmation. The drawing provided would rule out the Enterprise design that Al describes above.
Does this make sense?
