Unknown Festungsbaudienststelle

[TiesG]

Hello all,

Bought a picture recently from a Festungsbaudienststelle on an (for me) unknown location. It seems the Dienststelle was situated in a vacation rental called Ida. It wouldn't surprise me if it is somewhere on the Dutch coast.

Any ideas are very welcome.

Maybe Festungsbaudienststelle Schagen under major Hientsch.

Thanks Erwin!
