I've done a search online for this but getting mixed results so...

Did the BSA Mercury S and Airsporter S models come with the lettering on top of the action finished in gold etching, as standard?

The photos I can find via search engines are inconclusive- some have it & some don't. For clarity, I'm just talking about the bit that says 'BSA Mercury S' & 'BSA Airsporter S' between the dovetail.
