The box says Encore, but Scalemates indicates this kit was first issued by Dakoplast in 1997, then Encore, then Eastern Express, and finally Modelist. As Marc mentioned in comments to the build thread the sprues match the ICM kit. I enclosed the wheelwells, replaced the wheels, and substituted a vacuform canopy for the awful kit piece. The model represents a generic Yak-9T of the 3rd FAC operating in the Kursk area, summer 1943.
