Hi Matt - in case you hadn't seen, there's three mentions of your Dad in Martin Bowman's excellent book "Battle of Berlin: Bomber Command over The Third Reich 1943-1945", contributed by Doug Curtis from his time on your Dad's crew. No further details of him specifically, but all good background to the ops he was on and the crew he was with.
