Hm, looks selfmade to me.. If I had to guess I'd say this probably started out as some variant of Futura and then (d)evolved from there.

thanks Franz for all your help.
I really like the R on the example - do you know what else might come close?

The large counter of the R is a characteristic of the recent House 'Neutraface' fonts. The display and the bold weights are similar to your sample, I think.
