Bringing A 100-Year-Old Lock Back To Life

This specific Corbin unit lock has not been made in 70 years. But the challenge of bringing the lock back to life was enough to make me volunteer to do the job.

Even with the hard life this lock has endured over the years, very little straightening or repairing was needed. The biggest chore was in cleaning each part back to its original luster. Photo 5 shows the case cover plate with patent dates. They don’t make them like they used to.
