ID: Squared yet Rounded Sans Serif

Okay, so there's a good chance this is a custom typeface, but it's worth a shot.

I've looked into it, found some similar faces, but can't quite pin this one down.

Any thoughts?

It looks similar to the old Rotring Isonorm stencil lettering. Various digital interpretations [[http://new.myfonts.com/search/isonorm/fonts/|here]], but none are quite as square.

thanks, that's definitely the closest I've seen so far!

CAT Design's TGL31034 implementation is similarly square but the lettershapes differ.
