JC, I have also misinterpreted the "palms". My Charlin has three of the crown/feathersa/stars couchant on a bed of barrel followed by St. Etienne. My minimalist "proofs of the world" says three of these whatzits indicate proof in finished state at 1300 Kg per sq. centimeter. The Acier Hercule stamps look like laurel wreaths which I suppose is what makes them "palms".
