Hi John,
whilst there were some very nice Rhodesian badges, I've deliberately stayed away from collecting them as there are too many SA badges I dont have; I dont possess one Rhodesian! I therefore am not familiar at all with their regiments. But a lot of Rhodesians did settle in SA and so its not a surprise to find the RR alongside the CGA.
I just think of looking there!
Ruwa, I dont have Dudley Wall's book tho' I've considered buying it but I'm confident it's a match for Owen's 3063.
