Way back in September 2009 the I-16 aircraft of the Xinjiang (Sinkiang) Aviation Unit were described in this blog here. Eduard have recently released a 'Weekend Edition' of their very neat 1/48th scale I-16 Type 10 featuring an aircraft of this Chinese autonomous region unit. There is no explanation on the box or instructions other than the description "Sinkiang Aviation Unit, Dihua airfield, China, 1941-42" so there might be some head scratching, or maybe it will just be assumed that this was a RoCAF unit.
On the simple decal sheet the six-pointed star is printed red which is a better choice than previous depictions of white but the probability is that it was actually yellow. From 1934 to 1942 the Xinjiang flag had a yellow star central on a red field but after 1942 the flag was yellow with a red star in the upper left quarter. The aircraft markings are as shown during their induction ceremony into Kuomintang service so might have differed when the Xinjiang Unit was actually training CCP flyers. I presume the finish was Soviet factory colours (!). In the photograph one aircraft at least appears to have the dark painted cowling.
