Curiouser and curiouser...Just printed some pics off for reference - and there's a jarring discrepency. Take a look at the front mandibles
A circular plate, vertically attached to the framework right? Now look at the next shot.
Instead of the flat plate, we now have something curving in towards the centre of the ship. And on the other side from it, a projecting piece facing foward. Are we seeing the same thing i came across with the Psydon Ship - photos show the ship some time after filming, when parts had fallen off or new parts were attached in way of repair?
