I did locate where the 'Particulars of HM Ships' were held with help from John Roberts.
But the bombsell I can't remember precisely where!
They are either in the PRO or Naval Historical in the Admiralty Library at HMS Victory Portsmouth Naval Base.
I have not looked through them yet as they don't appear a priority and I'm purely looking at Operational things.
They look a bit like the Pink Lists to me in the sense you need to use other sources to cross-reference with them as their a bit iffy and have gaps.
Here I've scanned a page for you from the 'Particulars of HM Ships' so you can see the format:-
I'm sorry I cannot remember precisely where they are, I'm juggling with so many sources and 450 ships!
at the moment its hard to just be able to navigate through whats in the PRO, let alone other locations!
Generally Phil I would consider only delving into the Ships covers at the NMM if I wished to understand the designing and/or rebuilding or a warship.
That's their primary value not wartime A and A's, though you have opened my eyes to them containing watime data on repainting.
Can you say alittle more on this please?
I believe a good thing for you to do is to contact the archivist at Priddy's Hard, the naval weapons depot which is now the Explosion museum at Gosport.
Ask them if they still have the armament return forms there from WW2 or where they are now located.
I've not done this yet as I have family who are moving to the Portsmouth area next year so in the future.
I was going to base myself there and do all the things in the vicinity of the Hampshire area in a few years time.
Finally with the MoD and their ultimate wisdom, well foolishness someone threw most of the wartime ships logs into a skips in the 1950s as ar says.
However anything above light cruiser, generally, should have survived.
Though I see your problem only Implacable's from 1944onwards is in the PRO:-

Though Illustrious looks better with only 1942 missing:-

My area with WW2 RN destroyers I'm left with virtually no wartime logs!
The swines!
P.S. John's not been contactable for some, I'll write to him on both our parts as I wish to know where there are again also!
