I bought the above injector thinking it was a Penberthy but further study revealed that the cones and arrangement of the overflow are different. There is no name on the body and any markings have been polished off. The internal arrangement of cones and spring loaded valve and plug are the same as those which can be seen in the diagrams for injectors fitted to Mann's and Wallis & Steevens below. It has since been identified as a Gresham & Craven injector.

Penberthy injector - from Willcox's catalogue

Extract from Willcox's catalogue with details of "Penberthy" injectors. This gives details of the standard range of injectors. I have another leaflet that mentions 428 and 430 injectors which are for steam wagons working at pressures of up to 250psi.  A section through a "Penberthy" to show the difference in arrangement of cones from the Gresham & Craven injector is included below.

Rex Injector

This is an extract from some trade literature in some Garrett documentation. There is no manufacturer's name but I suspect that it was produced by Whites. The Rex is described as a "Penberthy" type injector. It was suggested that the mystery injector might be a Rex; but if the position and inclination of the plug at the side of the overflow is considered, it suggests that it is more like a Penberthy than the Mann and Wallis & Steevens injectors.

I can't remember from where I got this copy. If it was you I hope you don't mind it being reproduced here.
