Kestrel F.G.A. MK.1 Experimantal Establishment

Hello Group,
I have this Kestral FGA MK1 Manual / Handbook which must have been from the experimental trials of the aircraft in Boscombe Down.
It gives a lot of performance data aswell as technical drawings and also cockpit schematics.
Test flight configuration with external load and Pilots observations.
On the front is a german VS (confidential) stamp, so I guess it was under review of the Luftwaffe DoD.
I no need for this and would like to sell it to a Kestrel or Harrier collector.
I don’t have a number in mind so please, any offer is welcome.
Thank you and best regards
