| Rolls-Royce, Limited Page 3 Here is our next suggested step in this effort. Arrange to use seven inch pulleys on this drive with the same groove angle that you used on this first test. Then let us have the new center distance on this drive just as soon as possible. We will immediately produce two more special belts for you to fit these new pulleys on the new center distance and send them over to you. Without equivocation of any kind we promise you that we will show you at least a one hundred per cent improvement on the next set of belts if you will follow this suggestion. Will you do it, Mr. Steadman? Cordially, [Signature] Export Division C.A.Winser:EB | ||
