As mentioned earlier the main Bell of the ship has an interesting story too. The whole story is really well summarised by a Lady called Claire Hunter and contains a lot of interesting photos some of which are shown below.

Here is the Link to her article which is a fascinating detailed read:

Photo #2 is most likely being taken onboard the HMS Cadmus. On the right of the photo you can see some rigging. If you compare it to the full view of HMS Cadmus in the next chapter and know that the Cadmus visited the wreckage of the EMDEN several times I think this is fairly safe to say.
