Vansell's TARDIS

Co-ordinator Vansell used a modified and unregistered Type 70 TARDIS which he used on his CIA assignments.

Arriving on Gallifrey, where his ship was scanned by the Chancellory Guard before he left, they believed that the TARDIS had been stolen before he came out in a panic when the Knights of Velyshaa were about to invade as part of a plan by the Sirens of Time to create chaos throughout the universe.

When the Fifth, Sixth and Seventh incarnations of the Doctor negated the alternate timeline created by the Sirens of Time, Vansell still arrived on Gallifrey, but he was confused as to why he was there before he left once more in his TARDIS. (AUDIO: The Sirens of Time)
