Frank Henriquez kindly scanned his Tsukuda box and a sprue. Frank reports that the planes are pretty indistinct; it's hard to tell the Me 109 from the FW 190. The Me 163 bears only a passing resemblance to the real thing, as can be seen in the detailed scan of the plastic. The box back has a printed 1/700 dirt airfield.
Three boxes of Tsukuda 1/700 aircraft models. The middle one contains the Me 163B.
