Should be usefull for interior scenes, it is at the right scale, so no need to change it.
All textures (including the normals and specular) are in the blend file.
EDIT: I added a grunge texture for the metal and sharpened the edges of the wood part.
EDIT 2: Modified a little bit shaders, and added enviroment texture and lights to get better context of the shaders.
Thanks skinman95. Very nice textures.
