Luftwaffe and Allied Air Forces Discussion Forum - Inspektion für Flugsicherheit und Gerät (RLM) Reports

I have a couple of very specific queries I hope someone can help with concerning the reports issued in the pre-war period by this body.

There are sizeable chunks of these documents at the IWM Duxford and the BA-MA as well as a scattering at the Deutsches Museum, however, small gaps remain across these holdings, specifically:

Teil III - Fliegerschaft - Are Volumes 9 and 10 available anywhere, either in an archive or private collection? My assumption is that Volume 11 is the last of these but if I am incorrect in that assumption, I'd be happy to receive confirmation.

Teil I - Statistik der Beanstandungen und Störungen im Motorflug - Is Volume 7 the last published volume in this sequence or do subsequent volumes exist?

Please reply on board or PM me as suits best.
