At Tamiya they really love the legendary Tyrrell P34 as they even own a full-size P34 that is on display at their headquarters in Shizuoka (Japan). This year the Japanese engineers decided to created an updated version of the Tyrrell P34 Six-Wheeler 1977 as raced at the Argentine GP with some changes, which include updated instruction on the color needed to paint the side mirrors, and livery location tweaks.
The Tyrrell P34 is known as the distinctive “six-wheeler” Formula One race car and its 1977 Argentine GP version featured a full cowl body design without observation windows seen on the side of the cockpit.
