Signature?

[Larry Paulick <larry@netkonnect.net>]

I am doing a ground up resto, and just took all of the parts out of 
the right door.  On the strap that goes from the inside door handle in 
the front of the door, to the door locking mechanism, at the rear of 
the door, there was a piece of what looks like masking tape, with the 
following; "R. Hinehart 8-19-65".  The car is a Mk1, B9471874 and this 
is around the time the car was built.  

Any clues, and has anyone come across something similar before?
