Brooks B-17 saddle. If you're already looking for one I don't need to tell you much about it. Color is "honey" i.e. light tan.
Practically new - I took this off a very lightly used bike I bought, as leather saddles are not for me. Some light scuffing from use on top but it has no deformation / butt imprints yet - that'll be your job on the next Randonée, but I don't need to tell you that.
Not that I need to tell you, but it retails for $175 new: https://www.brooksengland.com/en_us/b17.html
