Vintage 1950s Model Oil Refinery educational kit produced by Models of Industry, Inc. for the Standard Oil Company of California. This "Learn-By-Doing" project was designed as a packaged activity program for classroom use, featuring materials for six experiments and the construction of a simple model refinery. The set includes original instructional handbooks, the "Oil" booklet, and various project materials such as silver-toned tubes, liquid asphalt containers, and printed diagrams. A fascinating piece of mid-century industrial educational history and petroleum memorabilia. Sold as-is, unsure if 100% complete.
