I didn't at all recognize the FR Rack in it's unfinished state. I didn't know that was even an option.
Unfinished? Well, it has a paint which I would descripe as silver-gray-metalic that looks very close to aluminium.
Seems that the black safari version is more common, but I didnt like the black (to strong) and the rails around the rack would bring any benefit for my kind of use - only drawbacks
