The Tempered Spring Co. Ltd. A quantity of springs EB.3256 produced by the above firm have been found to have defective grinding at the ends. After discussing this matter with Mr. Base we are of the opinion that this fault can be corrected by regrinding at RR. Will you please arrange to issue an instruction to cover this additional operation. By adopting this course we shall avoid the possibility of a shortage. BY/NS.{Norman Scott} NS{Norman Scott} | ||
