Its only the specific roller buckles that have the metal roller, for e.g. the Stainless West End Roller or Brass West End Roller . Neither buckle is an official option for the Bakers AN but you can either order through me or leave us a note at the checkout as to the buckle you'd like. I'm afraid I haven't a photo of the leather roller I'm afraid, but we just stitch a thinned bit of leather in place of the metal roller.
Hope that helps!
