Originally designed as a simple 4mm scale chassis this has upon request been blown up to Gauge 3, axle holes are designed as 6mm to be reamed out. Some details have been thinned also. The bulbous plug at the front is due to the initial re-scale and needing to fit the body that was thinned out here to reduce cost. As a result this chassis isn't a finescale representation, neither was the original intended to be although as is normal feel free to add or modify details to suit. Walls are nominally 3mm thick so should be sturdy.
