Type 30 Mark III
From Tardis Wiki, the free Doctor Who reference
A Type 30 Mark III was a variation of TARDIS. Rallon noted that a Type 30 Mark III would have been more comfortable than a Type 18, which he, Millennia, and the First Doctor had taken when they had left Gallifrey to meet the Celestial Toymaker by accident. (PROSE: Divided Loyalties)
