Does anyone have any information regarding where the following crew served prior to being posted to 35 Squadron in July / August 1942?.

John Hilton Brown (Pilot)
Gomer Donald Waterer (Navigator)
Albert George Murray Coulam (Air Bomber)
David Aitken Sibbald (Wireless Operator)
Patrick Flynn (Air Gunner)
Stanley Seymour Vinicombe (Air Gunner)
Alan Tacey (Flight Engineer)

I recognise that they may have come straight from training, but thought I would see if anyone knew if they were with any other operational squadron
