maybe it is of interest for you that on the last picture in strils email from the 01.11.09 there is an interesting emplacement visible. It is a german concrete emplacement for a single 10 cm Kanone in Schirmlafette.
As mentioned those photos are linked from Tore Eggans website.(link below)
There are several pictures of this gun, and other interesting photos of french fortifications.
