Model resources? Penumbra entities and static objects?

[Slith]

Two things:

I'm wondering if anybody could recommend any model resource sites where it's possible to download models for using in your custom story (with no licensing restrictions)? Would be awesome as I have next to nothing modelling experience but would love to add new stuff that weren't originally in the game.

Secondly, this might have been discussed before, but concidering I also own all titles in Frictional Games previous series Penumbra, it would be awesome to get to use resources like entities and static objects from those to be able to make a mod taking place in a more modern setting.

Even being able to just use the flashlight, though probably having to replace some core files, would immediately give the possibility of a modern setting e.g. a man inheriting an old castle and goes exploring.
