QTR-Quadtone RIP

Is there a source file for the 21 and 51 step wedges?  The ColorPort download only has color targets available.  I did a Google search and cannot find any B/W patch data sets that are compatible with ColorPort; there was an old link posted by Ernst Dinkla from several years ago that is no longer active.  Are you aware of the two data sets?  I don't see any in the QTR download.  Before I start to create one, I thought I would ask.

You can see the L* curves for the 3800 here: http://www.outbackphoto.com/printinginsights/pi045/essay.html#20070123 but you need to scroll down to about the middle of the page. I'm on a Win7 machine and just went through making profiles using ArgyllCMS to generate and read the patches (i1 Pro to read them). It all worked fine and I could see the difference in the patch set by reading the unprofiled patch set and the profiled patch set. You can see the shift in Excel quite easily. I found the shift to be in the middle of the contrast range and that shadow values were relatively unaffected.
