Thanks again Zoran. I still think EN455 / G--R COULD be 81 Sqn.; on 20 April 43 Sgt. D W Rathwell RCAF ( 81 Sqn) shared an Me109 in her on a sweep to Bizerta. He had gone to 81 in N. Africa in Dec. 1942 and Malta in June 43 (he went to India with them in Nov.) flew 132 sorties in 81. By July EN455 was with 154 Sqn. flown by Sgt. Groombridge.
I suppose it's possible that Rathwell "borrowed" EN455 from 87 but they were not based nearby in April. The caption to her photo says Souk-el-Arba but 81 Sqn. was at Soul el-Khemis a few miles away.
Regarding the underside colours, the Mk.Vs which came from the CBAF factory in Desert scheme (the 5th order in ER series and some ES) had very light undersides, lighter than regular Sky; maybe Sky Blue, both were thought too light for N. Africa.
Of the 4 colours, Sky Blue was lightest, then Sky, then Azure and LM Blue darkest.
