Bill, The Ferguson Britt sporrans are the only ones I've seen with the rounded cantle made of leather. Let me know if you find others!

I did post a thread a while ago with pictures of my personal FB sporran. Maybe you were thinking of that? I didn't bother searching for the thread, but here's a blog post with the same pics.
