X8673 X5670 In EFC {E. Fowler Clarke - Electrical Engineer} 1/T.7.2.29, EFC. {E. Fowler Clarke - Electrical Engineer} confirms that EG.2 Morganite brushes are satisfactory as alternatives to Le Carbone Z. type brushes. In order to take advantage of this, we should order the 1st half of each series in EG.2 Morganite, and the second half of each series in Le Carbone Z. type. It is useless having an alternative unless we check it by constant use. BY. {R.W. Bailey - Chief Engineer} [Signature] | ||
