Let's recap: when the car got its engine at the factory, the engine was stamped with the frame number. The body was then put on the frame, and that number was never visible again, unless you were to lift the entire body off the frame again.
The engine/frame number eventually became the VIN. When now another engine was installed, no number that had any reference to the car or the paperwork was visible anymore. Unless you were to lift the body off the frame, you'd never know if that was the car that corresponds to the VIN on the title. Therefore, people either stamp a visible part of the frame (i.e., under the floorboards) with the VIN, or, less invasive, just mount a plate with the VIN on the firewall, so that the good DMV inspector doesn't have to order the car owner to remove the body from the frame. Does that make sense?
Here's the data plate I fabricated for my Model T Speedster:
I should mention that registering a car to the engine number was common practice in the US in the 1950s and even early '60s. We had plenty of cars where the original engine was gone and no number existed anymore. A plate is an easy fix for that.
