| To EH. from R.{Sir Henry Royce} ORIGINAL 6th February, 1919. RG{Mr Rowledge}/G6219. [Handwritten Annotations] Copy 5876 3 4 [End of Annotations] X.3231 [crossed out] RE BIJUR DYNAMO. X 2631 With reference to the Bijur dynamo, I am quite in agreement with you sending the one from 49 GB. to replace the one which is here belonging to the Packard Car. It should be ready to fit the same bracket, as the plant is in daily use for the office. [Handwritten section] Mr Clarke may be coming next week and might buy this together with other electrical parts which will serve for models to guide some calculations. We are allowing for 60 watts as the output for the 20 HP car dynamo. i.e. 12V. 5 amp, we set cutting in at 8 & 900 revs = 600 Engine Revs will this be about right for a small limousine.
