These are available at the Mack Shop. Dump and mixer versions. My opinion is that this is an average effort at best.
The cab looks very accurate. However, the front tires and wheels look to small. The exhaust stack looks like an after thought. No mud flaps?
They also appear to be using the old Conrad dump body used on the IH Paystar from the 1990s. Seriously?
The concrete mixer version also has a very basic generic mixer unit with minimal detail which looks like it could be old tooling from the 1990s.
First Gear, Sword, and WSI all have produced very accurate detailed version of the older Granites. This isn't even close.
Sorry for the rant.
