Tobruks

The harbour of Zierikzee lies inland. The entrance of the channel to that harbour was defended by a 3,7 cm gun in a tankturret. This is W.N. 341H. It shows two tobruks, so we think that the high one was used for observation and communication.

The modern bridge across the Oosterschelde is at the back. For observation ...

... and communication, perhaps a Lichtsprechgerät.

The tobruk for the tankturret.
