For me the probability of recovery looks something like this starting with the least likely and working up in probability:

Feast of Steven				never telerecorded
Mission to Unknown remaining DMP episodes				never sold abroad
Tenth Planet Power of the Daleks Ther Highlanders The Underwater Menace The Moonbase The Macra Terror Evil of The Daleks				sold but all prints accounted for
Galaxy Four Myth Makers Massacre Celestial Toymaker The Savages The Smugglers				all sold to Sierra Leone
Ice Warriors Web of Fear Fury from the Deep Invasion Space Pirates				all sold to Gibraltar and unaccounted for
Abominable Snowmen Wheel in Space				sold to Nigeria (with EotW and WoF) and to Gibraltar and unaccounted for.
Macro Polo Reign of Terror The Crusade				sold to multiple countries which are unaccounted for.
