Sorry breakwell, I only have 654 in my log book, I imagine it was WK654. The next time I flew it I only entered it as X, no doubt its sqadron letter. I think it was really intended as the target tug for 29 Javelin squadron, though I don't remember any air to air firing going on then, which is no doubt why NEAF had forgotten about it till I was idiot enough to remind them, instead of just asking the squadron boss, as I had before, while doing my day job on Canberras!
