The age of the tank was probably important enough to record the built date clearly on the tank.
Yes, but the built date for the tank isn't the date stenciled next to the weight, it's the built date at the bottom of the tank data at the right end of the tank. There's also a built date on the frame. The three dates are most often the same, but not necessarily so. A tank of a given age can be mounted on an older or newer frame, and sometimes a tank car bears a weigh date that's newer than the car.
