Indeed, I will try to provide as much history as I can of any SeaHawk, but I only recall getting hints about an example in Ireland, through seeing a broker's advert for one, probably in 2005! The only reason I remember it was because it was accompanied by the photograph you see in the black bordered handbill you see at:

Isolde which, to date, is the only other example of which I know.
