Damn, Yves!

Leave the easy ones for us at least.

There is very little difference between News Gothic and Trade Gothic. News Gothic was designed by M. F. Benton for ATF hand-set metal. Trade Gothic was developed many years later by Jackson Burke as a copy of News Gothic for setting on the Linotype system. There are only a few characters which differ noticeably in design (the cap 'Q' comes to mind). The main difference, I think, will be that the set of Trade Gothic is a little looser due to technicalities of the Linotype system.

But digital News Gothic varies considerably between different foundries. I once provided a quick comparison here on this thread.

Thanks for the link Kent.
If the sample was bigger, we might even be able to try and identify the foundry.
