This week I managed to pick up a copy of the sale catalogue on eBay, and it makes interesting reading.
There are no photographs of the items on sale, and no estimates are indicated.
It is divided into roughly one episode per page, on which all the lots relating to it are listed. One or two publicity stills from the episode are included, which may or may not show the items being listed!
As usual I have separated the items by Doctor era, and you can see the rest of the items here:
Here are just the lots relating to the Fourth Doctor era
Robots Of Death
The Invasion Of Time
The Androids Of Tara
The Creature From The Pit
The Horns Of Nimon - Full Circle
