Probably talking about the old Orange head. Those died in the mid to late 70's at best as all the 2 series combines used the Black heads starting with atleast with the N introduction in 78.
I think you are right on both accounts John. I don't know why but it seams as though the Aussies call orange red for some reason. The black heads of the '80's are sure fine Johnboy but the Huggers of the '90's are surely the way to go if you can swing it.
