Pete, As Maco mentions Rares did do these, I'm pretty sure they still do the shield triangle badge part.
However, the actual Special script part they stopped doing because the pins on the back didn't line up with the holes in the body.
It's a shame really because the originals are expensive to get re-chromed because of the die cast metal and they are getting harder to find
Maybe Ken McLean could ask Rares to consider re doing them with the pins removed and a modern sticky back ? as the shield part goes over the top and locates and secures the script part anyway
