Good day folks, I just bought one of these kits. while it says on the instructions that this is an all stell 40' flat built from 1928, I had a hard time finding the technical data. The dimensions I can do myself, but I would need the weight data (empty + max load), brake type (if fitted), and max speed allowed. Can anyone point me in the right direction? PS, how much does an axle weigh? looks like there are quite plenty of them on the car, too many maybe?
