did you get this on google and did you read this Yak-9T "White 66"
347 IAP
Artem Nikolov
winter 1944-45
This aircraft is an interestingly re-painted Yak-9T photographed in Poland with the 347 IAP during the winter of 1944-45. "66" is thought to be the personal mount of Artem Nikolov, who was later a leading engineer in the Soviet space programme.
"White 66" wears a solid-color AMT-12 camouflage, a color somewhat unusual on the Yak-9, but common on Yak-3s and La-7s. This coloration was certainly applied in the field, and "66" appears to have been completely refinished in this way, the color demarcation being quite soft. The spinner is red, and the national star borders were rendered in yellow. The small tactical numeral was painted on the rudder in a very old fashioned manner. The Order of Lenin emblem seems to be located on a un-repainted patch of the original scheme, apparently AMT-4 green.
