That's a swift. I have one. More narrow than the Pro, thinner leather. It's a little too flexy for my tastes.

One other thing..... When measuring the width, I assume it's measured at the widest point outside edge to outside edge? If so, my most comfy saddles are in the 150mm range.

You talking to me, you haven't even seen my arse yet.......

bottom is the very very lightly used swift I'm selling (ie... it was mounted ridden maybe 3 time for less that a total of 10 miles and customer decided to return it and get a softer saddle). The narrow does not have copper rivets and I don't have it in stock. Hope all this info helps.
