Caz, I know someone who should be able to get the contact details for the SIB and I will PM you them tomorrow so that you can set the ball rolling.
Good suggestion about the gate-guardian. Beagle was absolutely correct about it needing a re-furb - an anhedral tail-plane???! Beagle is so right about some things. Pity his comment about Benson's operational commitments at that time was shy of the mark like many of his offerings about the rotary world.
Hopefully, somebody at Benson will manage to source Alec's items soon; the lack of progress is ominous.
