These are a really cool piece of Oregon history. They look to be blue print engineer plans possible from a student at Oregon Agricultural College (OAC), which is now Oregon State University (OSU). They are from the 20s. Most from 1926. There are several original drawings along with the tracing of them. His book with his name in it and a few other misc. items. Let me know if you have any questions. Very cool stuff. Thanks.
