Narvin's TARDIS

Coordinator Narvin used a TARDIS on missions. It was a "top of the range" Type 400 TARDIS, far more advanced than the Doctor's Type 40 TARDIS, which Narvin referred to as "scrap".

After Narvin lost his own ship, and when Josiah W. Dogbolter was defeated, he demanded that the Seventh Doctor take him back to Gallifrey. (AUDIO: The Quantum Possibility Engine)
