http://retrospicere.narod.ru/library-books/book_998_2.htmБомбардировщик сверху красился в ?защитный? (зеленый с желтоватым оттенком) цвет. Состав был таким: 42% крона, 27,3% олифы, 25,5% умбры и 1% сажи. Снизу самолет был светло-серым: 34,84% литопона (смеси солей цинка и бария), 34% свинцовых белил и 31% олифы. Внутри машина красилась в серый цвет: 31,6% литопона, 31,6% свинцовых белил, 2,2% крона и 33,8% олифы.
