Hi Olli , yes Hendon do hold T9 drawings,but they would probably charge you for them. You could try Bruce at Classic Aero at Thruxton as they are finishing a T9 at the moment. Whether they would oblige im not sure but worth a try.

I have been in touch with Hendon and i have been sent a list of all the drawings they hold on the T9, now i need to work out what ones i will need to produce a model. I will also try classic aero and see if they can helo.
