click (sidetrackscalemodels.com) for several larger than life photos of their DSP&P 191 model.Wish they would do an as built version of 51 with Nesmith stack and Baldwin cab.
And maybe an early conversion smokebox front like 191 has and probably had from early on.Check the Baldwin doubleheaded wth the Brooks in the Hancock photo.
Robert, contact them and see if they can't build one for you. I can't seem to navigate this website very well, but I did see where they claim to build custom models.
