Quite a few years ago, I found in the weeds off a right of way one of the
black ACI plates that had finally given up and detached itself from a
passing car. Based on the barcode (starting on the left), the N&W was the
car owner (stripes 2-5) of car no. 12905 (stripes 6-11). Stripe 1 is the
"Start" and stripe 12 is "Stop" with the last stripe (8) is the check digit.
This has been hanging in my basement, but I am willing to part with it for
the archives.
