Great work chaps.
Penton Hook to me always conjures visions of Pike Fishing probably due to the Collin Willock book, "The Anglers Encylopaedia" that I had in the 60's.
Therein was a picture, (if I remember rightly) taken at Penton Hook of a chap holding a Pike wearing a Trilby hat and a long-ish raincoat.
So, from then on I always associated Penton Hook with Pike . . . . . . .
