Hi again Reinout
Regarding the Marine archive, I would say that it was open for "authorized" researchers already before WW2. During WW2 it was probably more or less closed.
It was American troops who first arrived to the castle Tambach after the War. They worked hard(in three shift) for nearly three Years after the War trying to microfilm all doucuments....but they were never able to finish their job...
This material(on microfilm) has been open for public research for over 50 Years I think, I actually have some of it since about 20 Years ago...
Regarding the "original" material I think that also this material has been free since mid 1950s, first at Koblenz then later in Freiburg...
A problem is that you indicate, has all material been open for public research...?
Those "archivarians" who works in the archive are in my meaning rather secret people, so all original material has probably not been open the whole time for public research....but the latest 20 Years it has probably been available for all....this has also led to that some material has been stolen..
I HATE THOSE WHO STEEL such documents...
I would say that the Marine Flying units are these which are best documented from the War....I have more or less rather complete unit rosters from many units..
The problem is mostly in the later Days of the War, with the
revolution in the Marine. But this material have been lost from the beginning..
With See 1 (which is a rather common abrivation) I mean
Seeflugstation Flandern I which was based at Seebrügge. This was also the "last"
official name of the unit
Regarding these German sources which credits Christiansen with 21 or 27 victories...I would like to see them..!!
There exist two(or maybe three) original documents from the War that give such numbers
BUT they refer to that
See I under the leadership of Christiansen scored such numbers..
And that is a completely another thing...
I can understand that British speaken authors/researchers could make such mistakes (translation errors etc) but I have more difficulties to understand that German researchers has made the same mistakes..!
You ought to find the Thread about C27 with searching for Christiansen, however I think the exact meaning of the thread should be "who really shot down the British Airship C27"
I can recommend a visit to Freiburg, and You can live nearby the archive for a reasonable sum of money. They have huge amount of material regarding See 1, which would take weeks to read through...
But for much of the confirmation material, You must read documents on higher levels. It was actually the Marineflugchef who confirmed or not the claims made by Marine flyers....
