Alan, you may have misread me, the models are no longer on display except for a small selection. The NMM and IWM collections habe been moved to the Chatham Dockyard repository while the Science Museum ones have gone into storage, initially in North London I think and are being transferred to the National Collections Centre near Swindon.
The models at Chatham can be viewed by appointment, I don't know about the Science Museum models.
The National Museum of the Royal Navy has a large collection of warship models which were last on special display in 2009 and are stored somewhere at Portsmouth Dockyard.

Yep - looks like I have - I went onto Google to check out what models are and which location and of course lots of info came back, apart from the fact that they were now not there!
What a shame they are gone. I'm from Sunderland originally and the museum in the Town Centre used to have a floor full of ships from the yards on the wear - naval and merchant. I wonder if they have also gone?
Looks like I've got my answer anyway, which is the scuttles/portholes are flush with the hull with no protruding surfaces. I've seen a few Dreadnoughts build with scuttles/portholes with bevelled edges on the brass, which are obviously wrong - some really nice builds as well, let down by lack of research. I've no doubt the builders would be gutted if they knew.
