Dating a vintage leather suitcase

Hi
Can anyone help with dating this suitcase? It has no makers marks, but a lovely interior. I was thinking 1940's maybe? Thanks

It appears more like a briefcase, rather than a suitcase, fitted for some special purpose.
How interesting, I'm looking forward to seeing what others say!
