Ah, thanks to you Stewie, more on Coulaux. Even a photo of the double chicken brand at the bottom of the page.
"The quality of the steel is marked made in descending order by three characters: a rooster, a Crown and a circle.Planing of Coulaux are rare and relatively new, but plane irons are often included in third-party tools."
