McPherson bought out Pearson a couple years back. All Pearson bows are now McPherson designs. At first, McPherson was still producing high end bows under their own name in addition to the Pearson line, but I' m not sure that' s the case any more.

I remember that sight, but haven' t seen one in a long time. I don' t think that thing is around any longer.
