Hi,
here are four screenshots of an UIL-2 on Scalemodels.ru.
http://scalemodels.ru/modules/forum/img_672672_1334381482_bscap0001.jpg.htmlIt is unusual for many respects: it has a straight wing, the black-green camo of z 18, and an unarmoured windshield.
Accoding to Gordon and Komissarov, UIL-2 were commissioned to Factory n.18 in February 1942, but the factory failed to cope and UIL-2 started to be produced in substantial number only in 1943.
All the photos I have seen before were of arrow-winged planes with three shades camo.
Regards
Massimo
