These changes improved performance, but handling was still poor. The third prototype was therefore fitted with revised slots, as well as the drag reduction changes tested on the Hanley Mark II, the revised aircraft being designated Hanley Mark III, demonstrating considerably improved handling.
[Barnes 1976, p.221-222.]
By the time that the Hanley Mark III was available for testing, the Dart, which was developed from Blackburn's earlier Swift, had already been ordered into service.
