The LCA is a terrific series - I've been using them a lot this last week or so, cross-referencing with other sources, in research for my BoB 'Hardest Days' project.
It's interesting, and a little odd, that, at the time, the Air Int crash reports could be quite comprehensive, or very basic (understandable with the latter, with so much going on !). Some have no known photos, the aircraft my have been a total wreck, but there's loads of information, including Werke Nummer, code colours etc etc, where other, intact aircraft, have been extensively photographed, but have very little information !
