If you are correct S'Land and I am sure you are. I would like to ask Geoff how well did the model fly as I understand that four prototypes of the A.D. Scout were built, two from Blackburn and two from Hewlett and Blondeau Ltd, and delivered to RNAS Chingford. However, because they were all considerably above the estimated all-up weight and were found difficult to handle in the air they were scrapped.
