I just ran across this thread from last year. I have this stamp in my collection - I think I may have purchased the stamp from Gaertner in 2009, because my stamp looks exactly like the scanned image (on piece) near the top of the thread. It is clearly dated 8 Nov 1945. Anyway, I have a very high quality scan and some literature on the subject if it is of further interest to anyone.
