Rhodesian Camouflage Trousers - Camo Bush Pants

These are out of my field of expertise and I am relying on a colleague who identified these for me. He says they are %Rhodesian and hasn't been wrong yet for me but if anyone out there has a different opinion I would much appreciate it. Photos show the pattern and the "busy" areas. Looks like one button has been replaced. That is typical of well used bush combat gear, together with the other repairs shown and the fading.
