Will you please make up one experimental silencer to the dimensions of the attached sketch. We should like the 2 ends to be detachable and all the buffers held in position by the means of slips so that they can be moved or removed as required. The whole job can be made in a light gauge material for test purposes. Rm{William Robotham - Chief Engineer}/G.H.Whyman. | ||
