Probably an early form of using the ships superstructure as a Radio Transmitting aerial.
The antenna next to it was probably the exciter
Array RN ships did the same but we used exciters
Slung from the masts and our funnels used as aerials never had these insulators.

Could be - and that was another answer I was looking at.
There's a total of 36 'bells' and, I believe, these vessels had 6 steam tube boilers, which equates to 6 outlets each.
Could be it's just me scraping around for an answer though  %) .

Could be but why have wires and aerials ? For steam vents ?


I like the radio transmitter option.


But please keep posting, someone must know what they are.

IMO, if I found something like this that I could not quite understand I would still try to model the detail, as accurately as possible from the photographic evidence shown, rather than omit it totally.

The wires could be probes and the control valves for the vents.

Ref the Steam vent idea, surely both funnels would have had them.

Having looked through my reference books I can't find any actual explanation on what the items were for.   I did note that the original picture looks to be of Z39 when in USN hands post WW2 and that the Dragon 1/350th kit appears to have included them.  I would suggest asking the question at Model Warships forum in the dedicated thread as there are plenty of German contributors that should have something to offer:

If you download the large file image of Nick's photo from US Naval Historical Center and magnify it the 'bells' actually look like lamps. They are screened from view fore and aft by shields so a good guess is that they were recognition lights.

If they were recognition lights, they
could be recognised by friend and foe
alike. Action stations at night invariably
meant 'Darken Ship' No lights to be shown
Red lighting by all deck accesses and
darken ship screens on every door.

Ned, the German Navy used coloured recognition lights in WW1 - see reports of Jutland night action. They were not left on all the time but used as challenges to unidentified vessels by flashing a predetermined pattern on and off. The RN used morse code letters by signal light for challenge and reply.

At Jutland the Germans managed to intercept part of the British code and flashed it back when challenged, this caused enough confusion for the Germans to get the drop on their opponents in several instances.

This would make sense of the fittings on the funnel. Flashing the lights on and off quickly was faster than sending morse and thought to be more effective in reducing vulnerability.

The US Navy used recognition lights in WW2 which resulted in the sinking of USS Monssen:

I knew about the recognition lights in WW1.
Just thinking about the advances in Comms
In WW2 had me thinking about my work on
Wideband Superstructure aerials in early 60's
when we still had a lot of WW2 ships in the fleet.
Someone will surely come up with the definitive
answer.

At last! Now we can all sleep soundly in our beds tonight.

Magnification of the US records image did show they were almost certainly lights. I suppose they were a sort of illuminated version of flag signals in a way. I wonder how successful the method was and to what extent it was used in practice.

Just another little historical byway which has been almost lost to posterity.

When I saw the post originlly I immediately thought a light signalling system but without any vessel details couldn't find anything on google for want of trying so I said nothing!  Wished I'd posted now LoL.  I wasn't that close though -I was fairly sure it might be a way of producing a pattern giving an "O", "X" "=", "I I", "." or "\" "/" etc.  Did I miss what vessel or class the original query was on though?  Someone at some point might be looking for the same answer!
