Dave Lefurgey is researching the life and times of his uncle Robert Niven who served under Cotton with the PDU and was instrumental in establishing the RAF’s photo recce procedures.

Dave would appreciate contact with anyone who is able to share information on Cotton/Niven/PDU to flesh out his knowledge of his uncle’s time with the PDU.

Mail to:dwblefurgey@hotmail.com

Many thanks on behalf of Dave.
