Definitely the nose from the Thunderbirds Mole.
However, the same drilling nose was employed in a late 1970's movie version of "Journey to the center of the Earth, in which a slightly disguised Thunderbirds Mole was used to begin the journey, instead of flloundering around in various caves and caverns.
I'm certain that Gary will be designing the Mole, not the late 70's movie prop.
I'm also very much looking forward to seeing this model evolve.
Kind and Respectful Regards my friends, Uyraell.
