Dear Sirs, We have a number of blue-prints at our Works giving the outline and dimensions of 1000 watt generators. Two of these prints bear the same number i.e. Z.1133 which shows a spigot diameter of 5 3/4" and the other 6 1/4". A further drawing Z1153 shows the diameter of 6 1/4" again. Will you please say which of these prints is the correct one to work to. We should also like to incorporate on all these 1000W. generators a hole in the shaft end 1/4" B.S.F. X 0.5" deep as shewn on your drawing Z.1100., referring to the outline of the 500 watt generator. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
