OSS reports on Bergkristall and kellerbau tunnel systems in Gusen Austria (Central Intelligence Agency)

To Whom It May Concern:

Pursuant to the Freedom of Information Act, I hereby request the following records:

WW2 German / Austrian underground factories for manufacturing and research
Bergkristall and Kellerbau tunnels reports, videos and photos. (German code names Esche I and II)
From 1944 to 1945 the OSS produced very detailed reports of the construction of the underground tunnel systems in St. Georgen Gusen near Linz in Austria. these reports included aerial photos from both 1944 and 45. There was detailed photos and reporting as to the production inside these tunnels. Some of these reports were released without the Aerial photos and other photo material attached, thus I would like these. Including all aerial photos taken from this area throughout the war until 1946
After the liberation of the tunnel systems in May 1545. The OSS produced detailed reports including photos of every piece of machinery inside these tunnels. Extensive reports were produced as to the production and research that took place inside during the war. Also it was documented what machinery the US removed before handing over the area to the red army. I am looking for all these photos, videos made and reports made of these sites.
Also the OSS had contact with the SS General Hans Kammler who was in charge of these, any mentions of these interrogations, surrender reports and later collaborations I would like.
Other agencies including British and Air force as well as technical services took part of making reports and gathering materials, information and photo documentation of these sites. These of course I would also like to see.

The requested documents will be made available to the general public, and this request is not being made for commercial purposes.

In the event that there are fees, I would be grateful if you would inform me of the total charges in advance of fulfilling my request. I would prefer the request filled electronically, by e-mail attachment if available or CD-ROM if not.

Thank you in advance for your anticipated cooperation in this matter. I look forward to receiving your response to this request within 20 business days, as the statute requires.

Sincerely,

Tino Von Struckmann
