Before there was LEGO, there were metal construction toys. Generations of budding engineers grew up assembling metal models prepared from kits by Meccano, Erector, Metalcraft and others. MOAH offers a glimpse into the model crafter's world of the early 20th century with Meccano-Mania, an exhibit of models by well-known modeler Charlie Pack. A giant Ferris wheel, a rocket-jet ride, a cable car railway and an unusual no-rail "railway" are among the operating models that go through their paces in this unique and enlightening exhibit. Many of the models are operating classics of their type; some were custom-built for this display. Be they whimsical, serious or historical, all are great fun.
