Manurhin is a trademark used by Chapuis Armes since 1998. It is used to designate the Manurhin MR 73 revolver family, manufactured at Saint-Bonnet-le-Château, France.
The genesis of the term “Manurhin” is Manufacture de Machines du Haut-Rhin founded in 1919 by Julius Spengler (Frenchified by him to Jules Spengler). The trademark was originally held by an earlier designer and manufacturer of the revolver. It now manufactures only military munitions.
