Re SWP, I really cannot recall if it was permanent on GR1, obviously not an option on 1A.

No, we had them fitted on the 1A too, the recce fit didn't change anything for the strike role; although we did get a more relaxed visit come WSU time. Of course, in the later years the weapons themselves were stored with the aircraft in the II(AC) and stabbed cat HAS sites.
