Jenner} and myself had a conference some time ago when we discussed Marine Reverse Gears. It was arranged that we should get some data of Joe's gears from Olley and also details of the fresh water cooling system fitted by Kermath. I suppose you have no news as yet. Joe's gears, I believe, are definitely lighter and more compact than the type produced by Parsons. Rm{William Robotham - Chief Engineer}/AA.{D. Abbot-Anderson} | ||
