Type 160
From Tardis Wiki, the free Doctor Who reference
A Type 160 TARDIS was used by Romana III to travel through a black hole to rescue Narvin and Ace. It was an obsolete model, popularly thought to have been decommissioned, but Romana said that they'd soon need all the TARDISes they had. It ran out of power on the return journey.
