This thing was fun to seek out. I guess this list is nearby complete, like 96% 
But here is found Collision Item types:
---List of Found Collision Item types--- - 7 = Dont allow Abe stand while in crouch in background (This is guess cause there is no situations of this ingame)
Only thing that makes me think is that walls seems have left and right wall. But as example i use left wall it can work also right wall. I have no idea of these walls why they work like this.  |
7 is the same of 3 but in the background
And there is one in scrabanian temple.
