Do T3 still have their "engineering outstation" or whatever they want to call it out at PIK?
Err I think you find that those J41's have actually gone home to mummy where they were intially made ie British Aerospace.
I would imagine that any increase in numbers of J41's on the British register will have come from the US from the desert. They will have a raft of Engineering changes to be made before they are fit for use in the UK. E.g TCAS fitted, Cockpit doors, BRNav and also any special stuff just for eastern eg a galley.
The fitting of the cockpit door would be a complete bitch with major structural changes which the line maintence hangers available arn't equiped to do.
