The BUA aircraft SIW, SIX and TDJ had the down turned wing tips. The RAF, BOAC, East African, Ghana A/W, did not. MEA might have. The prototype bought by Laker and immediately leased to MEA did I'm sure.
They had non drooping kuchemann tips on the C.MK. 1, Super (K3,K4)
I never worked on or ever saw a C.MK 1 (72-92)with a probe fitted. The fuel plumbing to the deleted probe was diabolical. There was no servicing instructions, SPs etc. for their inspection.
