Irving Braxiatel owned a Type 80 TARDIS. (AUDIO: Death and the Daleks)
After Braxiatel refused to leave Dellah for Gallifrey, the Time Lords recalled his TARDIS, (PROSE: Where Angels Fear) but he was once again in possession of it when he ran the Braxiatel Collection, disguising it as his office.
When the Fifth Axis occupied the Collection, they attempted to learn the whereabouts of Braxiatel's TARDIS and were ultimately unsuccessful in acquiring it. Adrian Wall offered to redecorate the interior if Braxiatel ever got bored of white circles (AUDIO: Death and the Daleks) and Braxiatel later gave it a jade colour scheme. However, he began redecorating as he did not care much for it. (AUDIO: Escaping the Future)
Braxiatel rescued Romana's third incarnation from a dead TARDIS by materialising his ship around her. (AUDIO: Intervention Earth) He later used his TARDIS to travel back in time to avert Romana's second regeneration, retrieving her second incarnation from the Moros. (AUDIO: Enemy Lines)
During the early stages of the Time War Braxiatel used his TARDIS to travel to the heart of the Obscura, return Ace to Earth, (AUDIO: Soldier Obscura) and rescue Narvin from the Project Revenant facility in the collapsing Kaiphos Occlusion. (AUDIO: Desperate Measures) He later used the TARDIS to rescue Romana from Daleks on Unity, (AUDIO: Dissolution) and then flew the ship through the event horizon of a black hole to reach the Beyond.
After Braxiatel was killed by the Ravenous, Romana used the ship to return to the universe, (AUDIO: Beyond) however was immediately ambushed and captured by Daleks. She and Leela later used the TARDIS to escape the Dalek Emperor's saucer moments before its destruction. Lord President Eternal Rassilon subsequently had the TARDIS diverted to the Cloisters so he could capture them. (AUDIO: Homecoming)
