Hi there, bit of a thread resurrection.
My late (d. Aug 25) grandfather was a pilot with 76 Sqn and flew sniff 2 on Grapple Z 'Burgee'.
While he was still alive, and thankfully before he completely lost all memories, we managed to claim his Nuclear Test Medal.
I've got his logs and some details about his time at Edinburgh Field/Christmas Island and would be happy to share with people interested.
