Great information and guesswork, Eric, mille mercis! Many thanks!

This first digit designing the Staffel of JG 104 is enlightening! So we do head for Fürth and thus unit... The surrounding seen in one of the two pics of "Schwarze 473" does fit quite well. A sandy soil, a small elevation in which those blast pens were dug out...all this fits well with the topography seen in the well known color shot of the Fürth dump, Summer 1945.

Franck, thanks for your confirming..and expert advice! And now, which G-14 you mean on my Flickr pages ?

Very very interesting... Thanks again to both!
