My Moto brochure from '76 shows a black GR with red panels and gold outlining. (Very sharp!) The specs have it available in silver or black, 531 throughout w/Nervex & Campy, Campy ders, Weinmann brakes, Brooks Pro, TA crank, 27" clinchers. The bike pictured in it was probably built in 1975, of course.
