I was talking to Martin Bower yesterday and he said someone had emailed him about the Dorcon ship from the 1999 episode of the same name but he couldn't recall which one it was and did i know?
So i go "wedge shape one, with the 1/24th Harrier refuelling probe stuck on the front, light blue."
That jogged his memory alright but it turns out its not light blue at all, but the same "Capri Blue" that i'm using for the Spinner:
And, looking at the ship photo again, you can see it on the the sides that the flash didn't hit so much. Goes to show, don't take things at first glance
