Notes
  1. The contract for A729 - A777 pre-dates that for A411 by two months. It is likely that this was for F.K.7 aircraft but cancelled and replaced by contracts for F.K.8s, the production version of the F.K.7 [3].
     
  2. Later alloted serial H4424 against contract (or possibly file number) AS.27755/1 but allocation cancelled [3].
     
  3. Contract AS.1252 per Bruce [3], AS.6285 per Sturtivant & Page [5].
