X.7430. For meeting customers complaints on existing cars and possibly for future standardisation if found a sufficient improvement, R.{Sir Henry Royce} wishes to try a small worm with a still slower pitch, namely, only .8 instead of .940, giving about 2.65 revs. of the wheel from lock to lock instead of 2.250.
