ABSTRACT OF THE DISCLOSURE Apparatus for marking a surface of a piece of metal, comprising a molten other metal spray gun assembly and a stencil assembly comprising a plurality of side by side arranged groups of stencils each being indexable to bring a se- lected one thereof to an operative position, one of the assemblies being movable transversely of the direction of indexing to enable marking to be effected by metal from the spray gun passing through those stencils which are in the operative position onto the surface whilst there is no relative movement between the stencil assembly and the surface. The invention also provides a method of marking a surface of a piece of metal wherein a stencil assembly, comprising a plurality of side by side arranged groups of stencils each being indexable to bring a selected one thereof to an operative position is maintained close to the surface with no relative movement between the surface and the stencil assembly and molten metal is sprayed from a molten other metal spray gun assembly, one of the assemblies being moved transversely of the direction of indexing of the stencils to cause the molten metal to pass through the stencils to form markings on the surface.
