The order office have pointed out to us that bracket D.75415 when produced in mild steel and chromium plated is more expensive than if it were produced in staybrite. We have no objection to using staybrite for this part and should be glad if you will issue the necessary instructions to change the material. E/Lid.{A. J. Lidsey} | ||
