Lidsey}1/AD23.11.31. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ EXPERIMENTAL EXHAUST MANIFOLDS. X4015 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ With reference to your Hm{Capt. W. Hallam - Head Repairs}/VA10/CM19.11.31, the remaining pair of malleable iron manifolds which you have should be suitable for chassis 7-AL. They are suitable for all C.I. head P.I cars - the aluminium head started on XXXX F2B series (C.L.numbers), 7-AL therefore should have a C.I. cylinder head. Possibly our previous memo in which we stated that the manifolds were suitable for carsup to E.2 series misled you - it should have read 'up to and including F2A series".
