Working on the assumption that was the right answer..... I'll pop up another question and it's pretty easy to keep the ball rolling.
When I started to take a really serious interest in fly fishing there were 'legends' regularly producing articles in Trout Fisherman magazine, a publication my father had largely dismissed as 'the trawlermans journal' largely because of regular articles describing a method of using leeboards and rudders incorporated called the 'Northampton Style'. The techniques that were developed then - over 30 years ago - are still worth knowing and a skill set the 'big loch' fisher should know a thing or two about
I digress.
Anyway, Steve Parton wrote a book that is as valuable today as it was when it was first published for the larger stillwater fisher titled "Boat fishing for trout" which includes heavy reference to techniques he learnt directly and indirectly from the 'source' of the Northampton Style.
The question is, who is credited with being the creator of the Northampton Style
