Rm {William Robotham - Chief Engineer} /Gry. {Shadwell Grylls} 4/R.3.3.37. We have recently sent you a pair of modified Lucas Mellow-tone Horns. Since sending them, we have found that even with the modification they are still unreliable. Sales are sending to you at Chateauroux(French test region) a pair of Delco horns. Will you please fit these up, and see whether they suffer from the same troubles as the Lucas variety. Rm {William Robotham - Chief Engineer} /Gry {Shadwell Grylls} , | ||
