This is a great find!  Released 25+ years ago in 1997, the Mobile Cement Mixer from Hot Wheels.

Collectors Note: This is one of a handful of Hot Wheels whose castings/tooling were designed by Corgi and later purchased by Mattel. They are some of the rarest HW out there, in this case there were only two variations produced. One in 1994, and the same exact truck in 1997 but without the "7" on the back.

If you collect Hot Wheels, Corgi or Construction trucks   this is a great addition for your collection! (1:64 Scale)
