This book from Weekend Chief (edited by J.C. Smith, Jr) seems to disapear from the Walthers HO Reference Book. I was looking forward to this book as demo locomotives (not the leased ones - the "Take it out for a test run" DEMO) are rare. Anyone ever seen a orange and white SD35? Or a red with a yellow bib SD24? Or a sunny photo showing Flexicoil trucks under the F-9 demo?
