Raw photos of grey step wedge

Hi guys, does anyone know where I can find raw photos (Nikon and Olympus) of a grey step wedge with large intensities range, similar to that one used in DPReview dynamic range camera tests (they call it Stouffer Step Wedge (13 stops range)). Thera are images on imaging-resource.com, but only with four stops range of intensities.
That would be a nice resource to have available, wouldn't it? One could check DxOMark results using information from that.
Both DPReview and Imaging-Resource (IR) generate these for all of the cameras they test as they use them for their "Dynamic Range" results, just they don't publish them. Why don't you write them and ask them to publish these results, with IR perhaps the most likely to comply.
I do not need this for every camera, only one raw file for Nikon and one for Olympus. I'm doing my small raw converter research/comparison.
