It seems that some Whirlwinds may have been armed with Nord SS.11s, according to this research thread on the WT Forums which I have taken part in:

It seems that a few of the helicopters of 225 Squadron, which operated HAR.10s, were modified to to carry SS.11 ATGMs according to the following sources:

Here is an audio recording from the IWM of Roland Roper describing his time in service. The excerpt is from the 15th reel of 24 from 10:45, with further reference to the missiles at 18:45, when being referred to as Nord AS.11s.

Borneo Boys: RAF Helicopter Pilots in Action Indonesia Confrontation, 1962–66 by Roger Annett may show a Whirlwind HAR.10 with what may possibly be SS.11 launch rails above the landing gear, which is attached below.
Not sure whether these would be related to the JEHU, but it could be possible that these were lessons learnt which had been put into action.
Any further information about this would be greatly appreciated.
