Jaguar Racing Cargo Storage box

Hello, I have just inherited from my Grandfathers garage a Vintage Jaguar Racing cargo storage box. I have no idea about its history except it has been in his garage for a very long time. I have scoured the internet looking for something the same, but so far I have not been able to ID it or value it. Can anyone help please?

Kindest regards.
