There was quite a bit of excitement... and wild speculation... last week regarding previously lost Doctor Who episodes being found in, of all places, Africa. (Not that there aren't African Whovians-- it just seems like an odd place for 45 year old Doctor Who episodes to surface)
Now we know what was found.
Eleven Patrick Troughton episodes were found- one complete story (The Enemy of the World) and most of another (The Web of Fear)... of the two, it's generally considered that the Web of Fear is the more significant find.
There was speculation that 100 episodes were found- this turned out to be mistaken. However, these are two stories from the Patrick Troughton era- an era that has been mostly lost to us.
