Nope. The PRB have incorrect journal lids. Both have the "ears" sagging a bit, but that is easily overlooked. Otherwise, the Wasatch are perfect. The PSC have the wrong aspect ratio. The Lobaugh, while crude castings, have the ears at the correct height and the proper journal lids.
So Erik, are the corrugations innies or outies on the PRB cars? Inquiring minds want to know . . .
