The telegraphs in Cod's CT are definitely the same type as the Batfish's. Pictures were too far away, though, to get a nice close-up view.
Btw, I am really impressed with Cod's interior. It's amazing at how much equipment is still in her and how nice of shape she's still in. Your CT, especially, is very nice. Everything is still there. No empty wall or ceiling mounts. No dangling, bare wires. Looks like she could plot and fire a torpedo if she still had to.
