Interesting find on my Corvette tach.
 

Have the dash out. I notice this on the back of the tach.

Is that a person's name under the date, Darren? Pretty cool.

Pretty sure. Wondering about the significance.

I would think that they had to pull a tach off the line at certain intervals to test accuracy thats what happened and the guy who did it had to sign and date it.

Date is 77 though.

Not off the assembly line. Maybe audited in the supplier plant, but it wouldn't be signed.
This is a later repair or calibrate job.
