The one I have has probably been modified.

It has a carrying handle or did have as handle itself is gone.

There is no key for the lock but two clasps fitted to secure it closed.

So it’s been repurposed I think to carry documents or something, I’ll never know.

Comparing with the other photos it’s I would say identical to that the brothers have.

It has no tray nor internal supports for one. However the tray could be a floating one, it just sits on whatever is in the box.
