First: could (should) be Gotham (Medium) artificially softened with an additional outline stroke
Second, some sans with a similar /W: Raleway (very close to your sample, some minor details off), Selaive, Neutraface Display (using alternate /W), Scala Sans, Bernhard Gothic, Koch, Regulator, Evolette, Old Republic, Arnold Samuals, Orson Casual (rounded), Lucy Samuels

Thanks for the feedback - 'Raleway' is great, only available in thin for print though by the looks of things. Artificially softened is right. I've always liked Houschka - never seen the 'donkey sanctuary' identity by the Allotment Nick - nice.

Thanks Ryuk!
