1. Agents Copy of bearing, and it is therefore our intention to drop the AC.6. which presents certain difficulties in production, mainly from a casting point of view. The one point outstanding, therefore, is the question of the oil groove on which subject you are going to let us know whether you will be able to mill this groove at your end or whether we shall have to make provision to do so here. Yours faithfully, For WELLWORTHY PISTON RINGS LTD., Technical Manager. | ||
