Yup.
I can't tell you how many times I've read, on this forum, comparisons between the "B17" and other saddles, without ever specifying what a "B17" is. Well, the comparison may be valid, or not; but at many times there have been more than one versions of the B17, and of course they have been making them for over a century, and a lot of the ones in use today are several decades old. It's not always obvious how old a saddle is.
The B17 I have is 3 years old. Have you owned one? Any recommendations on similar saddles? Thanks.
