Sorry fella I don't have the reference, but when I had to sign the new terms along with my accepting my crown, the only thing that changed was my right to call myself an AEOp and I was supposed to wear the new Brevet.
I still call myself an AEOp, and still wear my original Brevet.
I was trained as an AEOp, and was awarded that Brevet, so why should I change?
It hasn't made any difference, and the "grown-ups" have never asked me to change my trade title or Brevet.
This was back in 2005, so things may have changed.
That said in the present climate I would go over it with a finetoothed comb.
