Of course neither of these is really satisfactory! Yes, they have the "sigma" E, and some of the streamlined feel, but little else. The R seems closer to Gill Sans or Humanist 521. And the B reminds me of Savigny. I wonder if this was based on a single typeface, or is a deft combination.

Edit: I just sent the question to Mark Sloan, the designer, who is based in Amsterdam. If he answers it, I'll post it here.
