An interesting letter reaches us from E. Williams and Co., Ltd., of Matlock Bath. Appreciation of the Girling parcelcar, which, by the way, was first described in these columns, and to the performances in service of which we have frequently drawn attention, is the keynote of this communication. Incidentally the company describes a small structural alteration which it has embodied on a Girling which is employed for mail service in the district. We are enabled to reproduce below a photograph of the machine in question. "No doubt," the writer proceeds, "many of your readers are using these useful little machines, and would be glad to know how we have imnroved ours. We fitted a. Claudel-Hobson carburetter, but were in difficulties as to how to warm it. Finally we adopted the plan shown in sketch herewith. The crankcase has a combined oil filler and relief valve close up to the carburetter. We removed the valve (a piece of springy brass) and substituted a i-in. brass pipe. This was attached to a copper tube by a piece of rubber pipe, and connected up to the water-jacket of the carburetter on one side. On the other we made and fitted a ball-release valve from the cupped end of a petrol-pipe union, and we soldered a plate over the threaded nut, which fits this, to prevent the ball escaping, leaving ample rcipm for the air to escape. The hot air from the base chamber—and very hot it is—now passes through the water-jacket and escapes by the valve, no cold air entering on up stroke of the piston. . . . The fitting of the Cla,udel-Hobson amply repays the cost of same in power. cool running, and lower consumption."
The photograph reproduced below shows the Girling, fitted with a box body, having side doors, the whole lettered and painted in the conventional Post Office manner. The most interesting feature of this combination, however, is the employment of a rubber-tired box trailer for the conveyance of additional mail matter. In justice to the manufacturers, it should be remembered that these little machines are not constructed to draw trailers OT to carry excessive loads.
