Reply to be addressed to John Marston Limited for the attention of AWD/BR FROM JOHN MARSTON LIMITED, WOLVERHAMPTON. MAKERS OF THE SUNBEAM CYCLES - SUNBEAM MOTOR CYCLES ETC. 24th December, 1935. Messrs. Rolls Royce Limited, DERBY. For the attention of Mr. Steadman. Dear Sirs, We are in receipt of your letter dated 20th inst., addressed to Mr. Southall, in which you refer to our letter of the 11th inst., regarding comparative weights and prices of Mark III, Mark V and Mark VI Matrices to Drawing E.59596. We should like to point out that in spite of the fact that the 84 m.m. Mark III Matrix is heavier than the 58 m.m. Mark V, the slight difference in price is due to the fact that in the Mark V Matrix the whole of the copper strip, both waterway and centre strip, is completely tinned, while in the Mark III Matrix the waterway strip only is tinned the centre strip being left in plain copper. Added to this you will no doubt realise that the Mark V Matrix is more expensive to manufacture due to its construction. We think you will agree that this explains the slight difference in price referred to. We can further discuss this matter when Mr. Southall pays you his next visit. We are proceeding with the manufacture of the 52 m.m. Mark VI Matrix to your drawing E.59596. We shall deliver this as soon as possible. Your official order has not yet arrived for this matrix but we trust to receive it in due course. Remaining at your service, FOR JOHN MARSTON, LIMITED. Yours Faithfully, MANAGER, RADIATOR & SHEET METAL DEPT. | ||
