As discussed with you will you please detail the modifications to improve the thrust arrangements on the Wraith water pump. Will you also please give us a scheme and details for the revised Wraith water pump which we discussed, with Tufnol bearings on the lines of the one we have tested and die cast cheapened construction. We hope to standardise the latter for D series Wraith and B.III if we can get it tested in time. Rm{William Robotham - Chief Engineer}/Std. | ||
