This will probably cause some derision knowing the attitude of many Ppruners to BAE Systems but have you tried contacting them at Brough or Salmesbury? There were certainly plenty of Hawk models supplied to customers over the years I was involved with the aircraft. If there is still a BAE Systems rep on Masirah (assuming that is where you are based), then he might be able to help point you in a suitable direction.
The last time I was on Masirah was to carry out an arrester barrier pull in trial with a Hawk Mk 103 and 203. The RAFO organisation of the trial was outstanding, one of the best I have ever participated in.
