| Contd. -2- EFC {E. Fowler Clarke - Electrical Engineer} 1/T21.9.22. RR Goshawk dynamo of the single field winding third brush controlled type. Lengths of various coloured wires as used on the Goshawk system, in accordance with table attached. so that the unit may be connected up in their approximate relative positions. If desired, length of tubing corresponding to those actually in use on the system should be used to thread the wires through, but it is suggested that tubing of larger dia. than that used on the actual system should be employed for convenience of threading. Particulars of these lengths will be given by the D.O. if desired. Attached is photostat copy of the arrgt. [strikethrough] [handwritten: connections] of the Goshawk electrical system.
