| -2- I find all these statements are very hard to reconcile, but since it seems to me that a harder iron or steel will score less than a soft one, we are quite willing to try, steel liners of higher Brinell. I enclose some curves showing how M.R. behaves on our cars. I am sending them for your information alone and expect no comment. I confess that if I had not been aware of the fact for some time, I would not have expected M.R. to behave in this manner when heated to 600°F.{Mr Friese} Yours very truly, FOR ROLLS-ROYCE LIMITED. | ||
