Pic credit in the later version of Mike Shaw's book is just 'BAe'.
As I assume that , in order to meet your request, BAe would wish to set up an IPT, before delivering a photo of Hunter 9s, several years later than required and with additional costs not factored into the original contract, you might be better off with 1(F).
