Chainring is a TA Specialites Syrius, not sure what the crank is. I have the same ring on my Space Horse with an older silver tiagra crank and it looks nice.
edit: just checked and it's a syrius not a zephyr.
The crank is TA also but you could get a similar look from most 80-90's square taper cranksets. Unless u gotta have that hidden bolt or matchy cranks and rings.
Also: campy rivendell grail bike with brooks trying to escape the seatpost.
