is that a genuine Yak 9 or a replica?
https://en.wikipedia.org/wiki/Yakovlev_Yak-9
In the early 1990s, Yakovlev started limited production for the warbird market of Yak-9 and Yak-3 replica aircraft using original World War II equipment and Allison V-1710 engines. These modern-built replicas using the Allison engines, have counterclockwise-rotation props, unlike the originals which strictly used clockwise-rotation Soviet V12 powerplants.
