Pretty sure, but not positive... The "pre-softened" version was available for a few years though; I'm thinking through the '90s. I believe the big rivet one was first called the Team Pro, when they appeared as production items on the Raleigh Team Pros in the mid '70s. Before then, I think all big rivet Pros were custom butchered. I've got a couple of NOS big rivet "Team Pro" saddles that aren't pre-softened, and date stamped from around '78. There was a time when I really loved the big rivet pro over all others, but the small rivet version rides as well. Now that I'm older, fatter and slower, the B17 is becoming more of the favorite.
