This is a 1978 NITTO 928 kit from their "Circuit Wolf" series. A popular race car manga in Japan. This kit was first issued in the US through ENTEX, and then later picked up and reboxed by AMT/ERTL. The mold and the pressing were in Italy at the time of this kits issue (1988), but it is not an ESCI kit. AMT modified the base to remove the battery box, and added inside flares to make it less of a toy.
