Will you please order the necessary material to manufacture 10 Intermediate Output Dynamos to the following particulars:- D.72238 Armature. D.72238 L.O.P. Armature. D.72417 Wiring Diagram. D.72240 Armature Coil. D.72241 Armature End Plate. D.72242 Winding Support. D.72243 Winding Support P.E. D.72246 Coil Separator. D.72244 Commutator. D.72244 L.O.P. Commutator. D.72245 Commutator Bar. D.71613 L.O.P. Standard Production - Brg.Brackets. with the exception of the commutator end brkt.D.72010.DC. The same casting will do but it will require re-drilling to our drawing D.72545. D.71615 L.O.P. Frame & Field Winding - Standard. Will you please put these in hand as quickly as possible and if you will let us know when they are ready we will arrange for their allocation for testing. These machines are required for Sales and Test Dept. as a preliminary measure before we adopt them for standard. With regard to D.72242/3 Winding Supports which really involve new dies, we agree for these 10 machines that they can be made out of the existing standard pieces by turning them down. BY/RD. | ||
