Andy.....
I have just lifted my copy of PFA Popular Flying Vol 18 No 2 Mar-Apr 1972 off the shelf.
Project No. 1569 was indeed a Triplane replica, but it was an Avro Triplane (probably more correctly a Roe Triplane). It was registered to an M Alliott of Camberley Surrey.
I have no recollection of the aircraft having been registered or completed.
