Here's a bunch of pics from when my uncle went through the operating engineer school. I think they date back to the late 50's or early 60's. He went on to work for Mercer-Fraser Co. My Grandfather also worked as a mechanic for them. As a kid I remember them talking about the various machines they ran and worked on calling them by the first part of the s/n (2u, 14a, 15a, 46a, 8t etc.) Never dreamed I'd own and run some of these machines. One of the pics is signed by all the guys in the class. Most are from central California and the bay area.
Ellery Marsh is my unc and is second from right in the first pic.
