This badge was posted on a South African Militaria website and claims to be an "Egypt" badge; see also description:

Description
This Badge came back to South Africa as a momento of the Desert War. It was the design of this badge which motivated Brink's Design for the one to the South African Tank Corps; we were actually in armoured cars.
"Quartermaster's Comment":- Quite well made for Cairo. There is a good touch of brass in the mix and the badge has copper lugs. The 4th/6th S.A. Armoured Car Regiment was Brigaded with the British 8th Tank Regiment at El Alamein.
I dont know too much about "Egypt" badges, presumably made locally, but why?
Also, RTR gurus, is it actually genuine?
Thanks,
Iain
