Good afternoon Ladies and Gentlemen,
Thanks to some help from Nick Millman, we shall shortly be releasing our newest colour ACRN36 US Equivalent Sky. This colour is intended for use on the undersides of various aircraft manufactured in the USA for Great Britain during the second world war. When Britain was ordering US built aircraft as a paying customer, the Ministry of Aircraft Production colours we are all familiar with were provided for US companies to match. Sky Type S was one such colour for which the US matches weren't especially close.
Du Pont 71-021 and Spec 3-1 No.323 Sky Gray were two of the common variants. Nick has provided me with information about 71-021 and we have developed ACNR36 accordingly. FS35622 is sometimes quoted as being nearest to Spec 3-1 No.323 but it's a bit too bright. Many modellers have simply used neutral light greys under their US built aircraft models, such as P40s etc.
