Many of you may not know about the Keystone Modeler. It is a free modeling resource available on the PRR Technical and Historical website and published monthly in Adobe. It is devoted completely to modeling PRR equipment. There is an ongoing series on PRR gons. There was a series on PRR X-29 box cars. All new offerings are reviewed and the issues can be downloaded for future reference. Yours truly wrote a brief article on how to backdate a GG1 to the original flat pilot version several months ago. An essential resource for anyone modeling the PRR or its equipment and you can’t beat the cost. It is free.
Love that Keystone Modeler! Beautiful model photography and terrific, informative articles!
