Fowler Clarke - Electrical Engineer} "GOSHAWK" 11. BALLAST RESISTANCE. SECTION 8150. We have released the above unit for production less the Resistance wire D. {John DeLooze - Company Secretary} 50197, we have however instructed that the wire may be bought on bobbins but should not at present be coiled to D. {John DeLooze - Company Secretary} 50197. We presume that you will soon be in a position to say definitely the correct length of resistance wire which should be used. [STAMP: RECEIVED, with a clock face and the year 1922] BY {R.W.
