5th London ORs commissioned into Air Services

[chrrip]

Hi

About 1500 5th London other ranks were commissioned in WWI and i have found short service details for most of the Army men in the medal rolls, LRB sources or Army Lists; my priority is to establish their 5th London service (which I have in the round) but it would be good to know what units the blokes were commissioned into; the Air Service info (RAF, RFC, RNAS) is a real gap. Any way I can quickly find the squadrons the 100 odd LRB men were posted to on commission or transfer? Is there an equivalent of the 'Armistice' Army List? many thanks Chris
