Danny, I think they are blemishes on the photo, sort of electronic magnet for dust and fibres!
I came across this just a few moments ago
My late father Flight Lieutenant Rodney C. Topley served 3 years in Burma as a pilot and ' A Flight' commander from 1941-4 , flying Vultee Vengeances-A31"s against the Japanese. In 1944-45 he was switched to Typhoon Tempests in Europe which he eventully crashed on takeoff one day. by the way , the 110 's motto is "nec timeo nec sperno" Best regards, and keep up the good work, John D. Topley
about one quarter the way down on the
Guest book 2001-2002.htm site. There is an email address for John Topley but it's 10 years old, but might still get him if you wanted.
I did send Fred a message some months ago but obviously he couldn't have been well enough then to respond, but glad to see he's still in touch!
