The Abu-Dhabi test was with a 7/2 was it not? I remember some images of the supposed test of the Mk.7 in egypt that was alongside an AMX-40 and a Challenger 1, I will try and locate them again.
Edit: ah no i'm thinking of the Saudi trials with the Osorio. Do you know what year the Abu-Dhabi trials were?
Edit 2: old copy of janes MBT says this and given its the same author im assuming the Christopher Foss vickers book also says this (i can check that tonight),
