A late reply from Nigel Allam
Hello all, I have only today been sent this thread from a good friend who knew of my fathers passing at the time.
The replies are correct they we have lent a lot of our fathers records and memorabilia to the HPA, and also retained the original flight logs of dads entire flying career; over 12000 flying hours as a test pilot!
I am happy to converse with anyone with a historical interest in this, or who would like access to material we have of the Handley Page days,.
