Thank you very much indeed for those replies. It is exactly what I needed. I talked to Bruce Clarke about this incident shortly after he had arrived to fly 748's in 1969 at 34 Sqn. But time dims the old memory and I recalled (incorrectly as it now turned out) that he was demonstrating asymmetric flight with No 1 throttled back which led to the spin. At least I was half right because he also mentioned the NTS system and the problem it caused.
Bruce joined DCA several years later and around 1982 died of a heart attack at work. Again thanks for the info it was invaluable as his son Glen now in his Forties was interested to know more about the incident.
