PHANTOM STEERING. X8430 [crossed out] X7130 4/9/26
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.
We send herewith N. scheme 2263. shewing the proposed worm.

[Handwritten note:] Scheme despatched Saturday separately.
