Subject: [CR] info on 6 arm Colnago cranks


hello all, i recently got a set of Colnago stamped cranks that have 6 arms. i have seen the 6 arm Ambrosios before but never this, looks later, and maybe made by GPM, as they have GPM chainrings. Does anyone know what the story is? Original owners says he got them as a gift from Ernesto Colnago. I have no problem believing that, but I can say I have not seen this version before. maybe early 1980s??? any help would be appreciated. photo here- http://img.villagephotos.com/p/2007-11/1287178/colnagocrank.jpg
