I've grown tired of waiting for Great West Models to make their HO concrete wall sections in N, or for someone else to pick up that great idea in N and run with it, but still want to model a warehouse similar to the one Dave Davis created in HO in his Modern Monster article in the November 2004 issue of MR.
To create my own prefab panels, I am trying to find an article printed in the September 1977 issue of Model Railroader on creating modern concrete structures using casting, hoping the article will have the general dimensions I need for the wall sections and ribs.
Does anyone have that issue and access to a scanner and would consider providing me a copy?
