I know others have posted about acquiring copies of the original Frisco 4500 class erecting drawings. Has anyone found anything or had any luck? I collect various erecting diagrams of my favorite locomotives and haven't had any luck with the 4500's. Any info/help would be appreciated and I downloaded the Frisco diagram book and the Frisco Modelers group diagrams as well. I am looking for the full blown drawings Baldwin would have supplied. Thanks!
