It didnt any alternative parts steve , is it the extended exhaust youre thinking ?Tempting, but the same markings for 601 are in the AModel Metal Moth kit. So the kit has alternative parts for the 60M? Now I AM iterested as the two AModel kitsI've got are the Genet Moth and the 'M' Metal Moth and I think I'd rather build this old kit than face another of these 'difficult' Russian kits...
