| 4516 HS{Lord Ernest Hives - Chair}/Ltd.S/MA. July 13th, 1932. Messrs. John Marston Ltd., Paul Street Works, Wolverhampton. For the Attention of Mr. T.E. Dalrymple. Dear Sirs, Further to our conversation here in Derby will you please obtain for us 2 Harrison Bonded core radiator blocks to the dimensions given on the attached print. The matrix should be 58 mm thick (i.e. using the increased length of soldered joints at the back and front.) The matrix as shown is a true rectangle having a tunnel in the middle, at the bottom, to receive a starting handle. We have shown the outside diameter of the tunnel we use in our own matrix and will leave you to determine the size of rectangle which will best accomodate it. In the meantime we are preparing radiator shells to receive the blocks and will forward them on to you as soon as we hear that you are ready for them. Yours faithfully, FOR ROLLS ROYCE LIMITED. | ||
