Re: HMS Glowworm in Norway 1940 colour question
I think "AP" is an understandable modern abbreviation of "Admiralty Pattern", words which can in fact be found used in full in contemporary WW2 RN documents. For example they are used in naming the colour chips of 507A and 507C in CAFO 679/42, in relation to 507A & 507C in the text of the Mountbatten Pink-related CAFO 789/42, and in CB3098R/43 in Table 5 on page 32 and in the text on page 36, again as part of the names of 507A and 507C. But here is another example: https://www.flickr.com/photos/51391079@N03/50351946211/in/album-72157716008672217/
More common though in contemporary RN documents etc was the use of either just “Pattern” or the abbreviation “Patt” in front of the numbers of the paint concerned. This is hardly surprising for internal RN usage since the word “Admiralty” was somewhat superfluous in that context.
I'd venture it's not only possible but likely that the dark hull was 507A (note that I have seen zero uses of the "AP" nomenclature in any official contemporary documentation - this AP507whatever appears to be a long-post-war invention much like modern prefixing "DKM" on to the front of Kriegsmarine ships) since even at the turn of the year the paints were described as matt finish. It's possible of course that 507B was still be used for undercoats beneath a matt finish coat into 1940 before it was ordered to be entirely discontinued, but that would be a moot point for model makers.
Call outs for 507B beyond 1940 can generally be assumed to be erroneous (until the end of the war).
FWIW my view on Glowworm in 1940 is dark hull with light upperworks.
Glowworm's colour scheme has been debated before on the "other site". The consensus, based upon the series of photos taken of Glowworm's last action through Hipper's range-finder, is that she wore the dark hull light upperworks (AP507B/AP507C?) scheme common on Mediterranean Fleet destroyers just before, and into the first few months of, the war. A couple of these photos, plus some artists' impressions of unknown accuracy, are online at https://www.wearethemighty.com/history/that-time-a-nazi-captain-recommended-a-british-captain-for-the-victoria-cross
. By 1940, it's quite possible that the AP507A had been changed to AP507A (same shade, without the enamel).
Incidentally the RN did not have destroyer squadrons at this period - although Glowworm joined the 22nd Destroyer Flotilla in November 1939, she returned to the 1st Destroyer Flotilla in March 1940 after her collision repairs.
I pulled out the recently released HMS Glowworm by IBG in 1/70tth scale. The directions show her in AP507 with neutrality colors in the gun shield. Until October 1939, she was in the Med which would be appropriate for serving in that theater. When she was transferred to the 22nd Destroyer Squadron for service in the North Sea and later Norway, was she still in AP507C? I was thinking that AP507B would be more appropriate. Which would be the right colors for her final VC battle with Hipper?
