A couple of years ago I helped a chap called Dick Steele, who also owns Sandown airfield, get his 1936 ex-US Navy N3N-3 onto a public transport CofA.
(photo linked from G-INFO, hence the copyright statement, which isn't mine).
He told me that he wanted this so that he could offer experience flights and big taildragger conversions.
Might be worth contacting him via Sandown and seeing if he's still in that game?
