Bike identification help (as in help me identify the model/brand)

I should have asked the guy at the time, but he had a nice looking gravel bike outside the co-op in Bradwell this weekend. 

Green frame (putty-ish green), Head badge looked to be 3 mettalic line art peaks (or something like that). Downtube had white lettering under the top-tube (making it hard to identify from walking past).  

It's not critical that I know, but no knowing is really irritating and my searches has failed hard! I also can't think of a place more likely to know the make and model of the bike, or probably even the guy riding it (I don't need to know that) 😉
