Thank you Arclite01. I have not been to Upwood since I was a schoolboy in the RAF Cadets, but I visited the local churchyard a few years ago to pay my respects to the Blenheim boys lying there. I did know Richard Passmore (and have read his book) and worked with him on Blenheim research. I seem to recall that he had a stroke and lost a lot of his capabilities a few years before he died. He was a teacher in the area in which I lived but at a different school from mine.
Wander00. I have not come across Bob Browne although in my researches I have collected several thousand names of people who served in Blenheims, many of whom of course did not survive the experience.
