| To By from E.{Mr Elliott - Chief Engineer} c. to CJr c. to Her. c. to Hs.{Lord Ernest Hives - Chair} ✓ c. to Sp{Mr Spinney} [STAMP] ORIGINAL [STAMP] RECEIVED [Handwritten] Hs{Lord Ernest Hives - Chair} GOSHAWK RADIATOR, FAN, COWLING, SHUTTERS, ETC. [Handwritten] X4240 (struck through) X4227 We send you herewith 2 advance blue prints of Lec 1588 and 1601. These schemes have not yet been passed by Mr. Royce but I think it is essential to let you know what is being done down here in respect to the above so that you will be able to make your arrangements with respect to what material will be affected and when the alterations can be brought in. Lec 1588 shews the radiator to the same dimensions as the wooden model brought to WW. but the top line of the matrix has not been altered at the moment to have sloping shoulders as suggested by Sales. This question is still in doubt. Lec 1588 was drawn in anticipation of having a large diameter overhead water pipe with 3 connections to the cylinder head of the engine but it is very easy to move the thermostat over to the other side of the rear tank and put on a connection suitable for the existing cylinder heads. This latter has actually been shewn drawn on Lec 1601 but the diameter of the connection to the cylinder head has been increased from 1" to 1.125 in accordance with instructions with which you are already familiar.
