Back when I was trying to put together a prototypical N&W coal drag, I gradually learned the overall lesson that most mainstream rolling stock you see is just paint schemes slapped on top of a generic design. So it goes with the MTH N&W hoppers - the hopper design is just some generic they picked for all their fishbelly hoppers with multiple road names slapped on top. Most people are none the wiser and / or don't care. But for the select few 3RS enthusiasts this does not cut it.
For correct N&W hoppers your most affordable (and possibly only) non-brass option is to track down the 16 unique N&W fishbelly hoppers Atlas O produced over the years. This was a monumental task for me and I eventually gave up. I never understood with the N&W being such a popular railroad why no one has ever mass-produced an affordable correct N&W steam-era hopper.
