I meant to add, this scheme, using Tamiya and Humbrol, are on my Seafire FR.47. It looks very nice and when I can take a photo later today I'll post.
No real match to FS for Sky. Acryl probably does a Sky (ANA 610), but if it's similar to MM 2049 Sky ANA 610 it will be similar to Tamiya XF21 -- too dark and too green. Acryl 4748 Duck Egg Blue looks closer (lighter and bluer) in the jar, but I haven't used it, yet.
EDSG is sort of close to 26118 "Gunship Gray", but in my opinion (just that) 26118 is too green. EDSG faded to a blue-gray in service. If you want, Acryl 4752 is supposed to be FS36118 (not a smooth finish), but again looks too green to my eye.
