Yep! Got to be in Kew somewhere. Don't know if the RAF museum might have some info. They used to keep some documents but I believe what they had was fairly limited. The problem I used to find was that when you went to Kew, you'd always end up with loads of documents which were nothing to do with what you went there for but were all fascinating!!! By the way. Does anybody know what happened to the Air Historical Branch? I guess their documents all went to Kew. Now, if only Kew wasn't so far away I'd have another little project!
