| X 4187 EFC {E. Fowler Clarke - Electrical Engineer} 2/LG. 31st. Jan. 1924. Messrs. Scintilla Ltd., Wellington House, Buckingham Gate, London. S.W.1. Dear Sirs, RE. AM6-G MAGNETO. 26485 With reference to the Magneto of the above type which we had from you in May last. We find the range and of advance of this Magneto to be in accordance with the attached sheet. We should now like to know if it is possible for you to supply a control spring for the advance of the Magneto which would render it possible for the full amount of automatic advance to be secured at 2500 r.p.m. instead of 3300 r.p.m. Yours faithfully, | ||
