FWIW-despite what its says about available crankcase colours in the instruction leaflet-I've never seen a black case Mk2 Doonside 75 anywhere-but I've seen all the variouis head colours over the years-my two are gold (#122) and black (#737) respectively. A black case gold head would look quite distinctive-a bit like the Irvine anniversary limited edition one....
