Two cast steel plane irons. This type of iron has been produced since 1850 to celebrate French steel production (until then molten steel was produced only in England). We know 24 different plane irons with the silhouette of Napolén (Pierre Bouillot "Les rabots"). Here we offer a Goldenber brand iron in an iron marked by Hippolyte Charrut, an iron merchant from Grenoble active until 1868.
