We have estimated the cost of manufacturing this design on a production basis, and the cost without profit comes out at £5. 6. 0 each. This cost must be regarded meanwhile as provisional, as Wor{Arthur Wormald - General Works Manager} is looking into the details of the job, particularly the labour, and he advises us that he hopes to be able to effect certain economies. We will issue a revised cost later on showing the effect of any alterations instituted by Wor.{Arthur Wormald - General Works Manager} Handwritten: Ammeter £1 " 15 " 0 ! Switchbox without ammeter £3 " 11 " 0 D/Rd. R^a | ||
