| X4021 EFC3/AD. 15th February, 1930. Messrs. North & Sons,Ltd. Whippendell Rd. Watford. Dear Sirs, Spanner for High Tension Terminal Heads of B.T.H. SC.12-7 & 9 Magnetos. You may recall that recently you supplied us with a small spanner with internal serrations suited to the above terminal heads, this spanner had a radius arm. It appears to us however, more convenient to use a box type of spanner for this purpose and we should be pleased to know if you would be able to supply a pair of such spanners of the box or tubular type. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
