Thanks again, that clarifies pretty much everything from T4s to Mk3Ph3, where and when, over a number of years.
As for dustbins and seaweed, we had a 206 Mk3 return to St. Mawgan with part of the dustbin missing. There were some ATC Cadets on board that trip, one of whom was enjoying the view from the tail end as scanner met water. He appeared unfazed on disembarking, probably thinking it was quite normal for bits of a maritime aircraft to submerge occasionally.
Happy days.
