| X4383 W/S. {Derby Works / Sales} Bk. {A. Birkett - Commercial Manager} from EFC. {E. Fowler Clarke - Electrical Engineer} EFC {E. Fowler Clarke - Electrical Engineer} 4/T27.3.24. RE 5-GII DYNAMO. Further to your PN {Mr Northey} /Bk {A. Birkett - Commercial Manager} /LH {Mr Haworth} 26/8/24, I am taking steps to have sent to you a dynamo, No.288, whereupon the only departure from absolute standard is that the machine is fitted with Morganite brushes of EG2 grade, which brushes we are proposing to standardise as a second string in case of failure of supply, having proved these brushes to be practically equally satisfactory to Le Carbone Z grade which are present standard.
