I visited the web sites and looked for more key letters, but it seems not to be one of the Sans Serif fonts I have in my Guide. It resembles T-26 Flux and also their Leger, but neither is exactly right. It also resembles DIN, but the stemless bowl on Telenor's 'b' does not match.

It seems to be a Sans I have not catalogued, so I'm curious about it too.

Look what happened while I was off hunting! Thanks Fabio. I guess that explains why I haven't collected it yet.
