"HERON(Experimental 6 CYL OHV 40/50 WITH PNEUMATIC F.W.B. air pump on camshaft, then Servo)".

We send you herewith N. sch. 1341. This shews a good many of the principle features on the "Heron(Experimental 6 CYL OHV 40/50 WITH PNEUMATIC F.W.B. air pump on camshaft, then Servo)", and we send it to you in case it may be of service, but it is not finished, and just at the moment we do not think we shall be able to spare the time to finish it. We should therefore like you to take some prints off, and return the original, together with 5 prints, to us.

It will be noticed that the Servo motor operating the brakes has been changed to the right hand side of the gearbox, and the brake operating mechanism modified to suit. As the gearbox is not yet complete we are not sure of the exact position of some of these pieces.
