Let me provide. I cannot provide data on an open source such as pprune, I'd lose my job for breach of confidence. But with your background I can direct you to a name and with his approval to cite you as a reference let us see. It is a straightforward matter of what can be said to whom, in what circumstances and how it may be appropriated, the rub being "if at all". But let's keep it simple. I know rather more about "baby" Boeings than Airbii other than the A319-200 with which I had a fling. If you pm me I will reply. No worries.
