Where are original documents that where microfilmed

[Mikael Olrog]

Hi,

Is there any way of locating the original documents that where microfilmed for NASM? There's some microfilmed documents with photos that I'm interested in locating the original documents to make good copies of the photos since the quality of the photos on the microfilm isn't very good.

Has anyone else here on TOCH experience in locating the original documents that has been microfilmed at NASM? Is there any way of tracing the microfilmed documents to the original document?

I know that some documents have been returned to Germany (Freiburg and also to Deutsches Museum where I saw some that I'd previously seen on NASM microfilms). Is it known which documents that where returned - and if so - can one locate a document in German archives from the known US designation it was given in US archival system?

I thought I'd ask here before contacting NASM themselves.
