Thanks all for the complements. As I stated, I posted photos of this model sometime ago, I think these are better shots. It was one of the models I built soon after I returned to modeling way back in the early 1990s,
The engine is the twin turbo Cummins that came with the kit. The flat roof is from a modeler named Alan Royer. He offered truck aftermarket items in the late 1980s to mid 1990s.
The Revell "Trucks of the World" series are still some quality kits.
