Ev.{Ivan Evernden - coachwork}/HH.

Rm{William Robotham - Chief Engineer}/CTS.{C. Trot Salt - Carburation}15/ML.29.2.40.

B.60 Connecting Rod.

We note that you have altered the drilling up the rod as follows:

RE.297-8. :- .156 hole.
Whereas before, it was -

EW.1641-2. :- .218

The Shop say that the drilling of the latter is a far simpler job, so we have agreed that they should revert to the original dimension.

In the meantime, we would like your verdict on this job, and the reason for the alteration.
