FOUR PORT HEAD. Water Pipes to Hotbox. --------------------- We send you herewith LeC.5710 Water Pipes to Hotbox to clear Petrol Pipes - Four Port Head, Ph.III. This scheme shows a modification of the water pipes from the hotbox to the top water rails to clear petrol and drain pipes, and involves moving the bosses on the top water rail as indicated on the scheme. We note, however, that the top water rail for "B" unit already has the boss in the new position we desire, owing presumably to an error in detailing from the original scheme LeC.5420. This means that the top water rail for "B" unit E.88887 does not require modification. Will you please detail this alteration and incorporate it in the LOP's. for the four port head for production.
