Just saw a service call sheet from 1982 and the numbers blew my mind
I was cleaning out the office at our shop and found a stack of old paperwork in a filing cabinet. One was a service call sheet from a building downtown, dated October 1982. The total labor charge for a full door operator rebuild was $127.50. Adjusted for inflation, that's over $400 today, but the parts list had a motor listed at $85. I guess I knew things were cheaper back then, but seeing the actual ticket made it real. What's the oldest piece of shop paperwork you've come across, and what surprised you about it?
