Model Builder Magazines were excellent and reflected the works of some of the great modelers of the time. It took me a couple of years but I acquired the entire collection. It was used as a reference to build my layout. You had some real talent in the hobby back then. I believe that Model Builder my have been discontinued as it did not appeal to the largest audience for model trains that was the children. Way back when , Madison Hardware had stacks of these magazines in their warehouse and I bought quite a few before they closed.
