^ Wow thanks for that Bingowings, very interesting stuff.
I'll have to watch the serials that lead up to The Sea Devils...
Terror of the Autons
The Mind of Evil
The Claws of Axos
Colony in Space
The Dæmons
I'm raiding my local library's Dr Who DVD collection (They've got a few of the above at least). I'll get The Master's debut in 'Terror of the Autons' on my next trip.
