[Nif Request] Collision Help!

[SlashSgt]

So, not so much a mod request, but a modification of a vanilla .nif request.
In the intro scene, there is a .nif that is to the left of the PA in the shot, of a pegboard with many weapons and tools on it. Well, turns out, this exists as a single .nif file within the game: Data/meshes/weapons/gunboard.nif

Now, I wanted to add this object into my game as a craft-able workbench item, and have succeeded, however, the item lacks collision and no matter what tutorial I follow or what collision I try to reassign from another object, the problem persists.

 

As such, I'm turning it over to the capable hands of the community, for people smarter than I to have a go at.

Cheers!
