Fr Ray Blake gives on his blog a couple of ancient and thoroughly charming videos of this splendid priest, from a Scottish gentry family which is in the stud-book, who ended his Anglican ministry at Holy Trinity Hoxton, the parish in which the English Missal originated. Then he became a cure in Normandy; and maintained to his death the old Roman Rite in his packed rural churches. It's well worth investing an hour of your time watching them. Tissier de Mallerais makes a very sweet cameo appearance as a youthful (practically adolescent) newly-consecrated Flying Bishop to confirm the kiddies prepared for Confirmation by this very Anglican-Patrimony old clergyman.
Helpful comments on my thread provide evidence that he was trained at King's College London (AKC=Associate of King's College), but only for a year. I wonder where he went to school.
