Thank you very much. That's interesting. Would the PD have added that at some event to prevent, or at least track the bike if stolen?
Yes. Some would could call it registered and it was used for proof of ownership in case it was stolen or lost. Not all cities practiced the same format and some you had to have a bike licensed. In Mesa AZ during the 60's the bikes were registered and tagged with a license plate. then the bike's frame and components were carved up with an engraver using the number on the plate.
