| Thanks for the replies folks - the picture I've attached shows the inside rear of the WTC The brass rod which operates the dive planes passes under the water/air tube then goes through the stern bulkhead via what is described as a quadrilobe bushing. The other side of this will be outside of the sub. do I take it that this bush successfully keeps out any water ingress? A similar operation in the Robbe has rubber bellows both sides of the bulkhead to allow movement but keep the water out. Hope I've made myself clear.
Cheers,
