The first deliveries to Ireland had green fuselages and aluminium wings but I've never seen that scheme suggested for the Chinese Gladiators in any of the documented sources. It is an interesting possibility. There are at least four known photos of Gladiators in Chinese service and two were reproduced in Andrew Thomas' 'Gladiator Aces' for Osprey but none of them are especially clear. The one showing an aircraft being wheeled out after assembly does show a "light" coloured leading edge on the lower wing that might be interpreted as aluminium but all the Chinese sources have them painted initially in overall dark green. One photograph (see links below) shows an aircraft with "light" coloured struts and undercarriage legs which have been interpreted as the under surface light blue in a later two-tone scheme. Personally I doubt there was much time to re-paint them once they entered service but there are two distinct differences in the way the four-digit aircraft numbers are displayed - with either large white numbers on the fuselage sides or small numbers on the fin.
A single colour painting showing Chin Shui-Tin in Gladiator 2809 ramming an A5M with his undercarriage on 3rd August 1938 over Liang Chia-tien, Hupei, depicts a dark green scheme with standard blue/white sun insignia on both wings, blue/white rudder stripes, large white fuselage numbers and a red spinner. Major Chin claimed 5 destroyed and 3 damaged in the Gladiator. Wong Sun-Shui also had claims for 5 destroyed and 2 damaged in the Gladiator. Both pilots were American citizens with Cantonese parents who were taught to fly privately in the USA and then volunteered to join the Cantonese Air Force. The Cantonese Air Force was absorbed into the (Nationalist) Chinese Air Force in July 1936. More about Chinese gladiators here:-
There are decals available for various Chinese Gladiators from Bestfong and previously from Kora with a resin spinner-less prop. The new Airfix kit usefully has a separate spinner as some Chinese Gladiators were flown without it.
Definitely worth modelling as the Gladiator's combat debut was in Chinese service and their story is a fascinating one that I shall be featuring at my blog shortly.
