Lets not completly destroy one of our best references -guys
I agree no reference is perfect -Hartmann is ultimately a compilation of other supposedly 'relaible' references and as an otherwise good reference book attributed Royo and Cire to Moser - Hartmann had noted that fact -for a long time I was taken in too and I'm meant to be a Moser expert.
When a completely new Baccarat signature turns up, different, in style, case and form from any seen before (in Hartmann or anywhere else). I'll still leaning toward a 'creative addition'
