Right, I took a look of what I have but the flag locker location after the refit isn't well captured (the number of pics that follow seem to contradict that..)

This pic of HMS Prince of Wales shows that a series of answering funnels are placed near the flag lockers.

Pre-refit shots show these funnels on HMS Hood as well.

The plans after the refit do not show these funnels, however, not all plans show all details equally well.

When I look closely at this IWN shot I do notice several halyards and they seem to be going to location next to the flag lockers.

Stills from various movies show some cleats and halyards not going to the flag lockers, but I cannot see the funnels either, or where these halyards start except for that one colour image.

But even HMS Prince of Wales it seems to be fairly straightforward, simply a few cleats. (And only one funnel, they did not follow the builders plans). So I suppose cleats next to the lockers is it. Perhaps they even tied them to the railing for the inner lockers, similar to this close-up from HMS Sheffield (left tied, right showing a cleat).
