I spent a lot of time looking at several sites and thousands of sans fonts. I never saw anything close. My suspicion is that there is a font with some alternate letters which don't usually show in 'test drives'. Do you have samples showing G, M and R?

Any clues about the age and origin of the sample?

Mike,
here are some additional samples, as suggested. G was only in bold.

They are from a company leaflet from about mid last year. I tried to look up the most used production suites and even word processors, but without success. How is it with alternate letters? I suppose I can only look them up one by one, right?

If it is from a company leaflet there is a chance that this is a custom corporate typeface, therefore not showing up in the usual places. Can you disclose the name of the company?

If it’s a British company and it’s a custom font, you may want to check the fonts on http://www.daltonmaag.com/ – they do a lot of corporate typefaces.
