I think that you're right about the Wehrmacht FFW bits Alex.
The answer to your question, I'd suspect is that German house clearers have discovered that the albums and photos they find in attics and which they used to be embarrassed about are now an easily saleable gold-mine !
Added to that, even the children of those who served in 1940 are getting old now and I can't imagine that finding out what Grandfather did during the war is quite as popular in Germany as it is in the on the 'Allied' side.
I find it a bit of a shame that the pictures are being removed from their context but I can't grumble about all the new BEF images.
