I’m something of a late-comer to Doctor Who. When I started buying the DVDs in 2010, I was so far behind I didn’t even think about which ones had yet to be collected. But the BBC kept releasing them and I kept buying them so that, eventually, we got to the end of everything that was not missing at roughly the same time. The audio soundtracks for all of the missing episodes do exist, however, and every once in a while the BBC will release episodes with animation to match the audio. I had assumed that, when they caught up to releasing all of the episodes that were not missing, thet they’d turn theit attention to animating more of the episodes that were. That has happened to some extent, but not at nearly a fast enough pace to satisfy me. (I will abbreviate the “Lost in Time” collection as “LiT.”) Here’s what’s yet to be animated…
FIRST DOCTOR
MARCO POLO – 7 episodes
THE CRUSADE - 4 episodes (#1, 3 on LiT)
GALAXY 4 - 4 episodes (#3 exists but is not available)
MISSION TO THE UNKNOWN - 1 episode (recently recreated)
THE MYTH MAKERS - 5 episodes
THE DALEKS’ MASTER PLAN - 12 episodes (#2, 5, 10 on LiT)
THE CELESTIAL TOYMAKER - 4 episodes (#4 on LiT)
THE SAVAGES - 4 episodes
THE SMUGGLERS - 4 episodes
SECOND DOCTOR
THE HIGHLANDERS - 4 episodes
THE FACELESS ONES - 6 episodes (#1, 3 on LiT)
THE EVIL OF THE DALEKS - 7 episodes (#2 on LiT)
THE ABOMINABLE SNOWMEN - 6 episodes (#2 on LiT)
FURY FROM THE DEEP - 6 episodes
WHEEL IN SPACE - 6 episodes (#3, 6 on LiT)
THE SPACE PIRATES - 6 episodes (#2 on LiT)
As episodes are animated/found, I will remove them from this post.

Galaxy 4 ep. 3 has been released as part of a reconstruction of the story in the DVD set The Aztecs: Special Edition. I don't know if that's available in your neck of the woods. I haven't seen it.
The recent The Macra Terror set has a partial animation of The Wheel in Space pt 1 among its extras.
