My original one from the 60s also says, “Not for Identification”.
The one I got to replace it when I thought I’d lost it in 2007 does not say that.
This also reminds when Sacramento put water meters into houses and said they were never going to use it to charge for water usage and of course you know what happened.
Just like the seat-belt law that said they could only ticket you if they had stopped you for something else, they assured everyone they wouldn’t stop you for not wearing one and now we have Click it or Ticket and we’ll taize you and kill your dog and stop resisting!
