[1e] Well of Darkness map tiles

By player33475, in Descent: Journeys in the Dark

With the arrival of 2e I have gone back and separated all my old 1e sets. I have managed to do so except I can't work out what map tiles came in Well of Darkness (the two dead ends are easy enought but the 1 room, 3 corridor and 4 intersection pieces elude me). I suspect the room piece is the large one with the dragon bones, but that's a guess.

Can anyone help? I guess I am looking for the shape/size and look (moss, tiles, dirt).

Thanks.
