Jack,
Pederson shared a Do-217 with three other pilots of 165 Sqn on August 19, 1942 at Dieppe. He was KIA on Feb 4, 1943, and is listed in the Nationwide Gravesite Locator of the National Cemetary Administration (
http://www.cem.va.gov/index.htm). I will write for his RCAF records (I would like his middle name and service number for my files) and let you know what I find. It will take 2-3 months however for them to reply.
Frank.
