Removing Falling Block Traps

[Bareheaded Warrior]

I don't have a copy of the NA edition, but I have picked up a few tiles in my travels and know that at least some are double sided, is anyone who has access to the NA edition able to do me a favour and confirm the following:

1. For the tiles/markers that have a falling block image on one side (by falling block image I mean the "rubble" one that matches the earlier editions) how many are there and what do they have on their reverse side?

2. For the tiles/markers that have a pit trap image on one side, how many are there and what do they have on their reverse side?

I have an idea...
