I had never heard about Sid before finding his name in a logbook and on the back of a picture.
This is what you will find on Airforce.ca about Sid Seid.

Flying Officer Seid has successfully completed a large number of operational sorties. He has attacked the enemy’s road, rail and water transport and destroyed at least eight enemy aircraft on the ground and damaged others. In September 1943, while enroute for an attack on a German airfield, this officer encountered an enemy convoy on the Zuider Zee. In the face of heavy anti-aircraft fire he made repeated attacks and obtained hits on at least three of the vessels. The long hours spent by Flying Officer Seid in careful planning and studying of tactical situations have been reflected in his outstanding record of achievement which has been an inspiration to all in his squadron.
I wish I had all those PL- pictures from RCAF files to show you…
