Yes, that's the old Professional. My favourite saddle. Some have huge rivets, some have more normal-sized ones. I have one where the leather has been cut away a little around the nose too - I don't know if this was a factory option or a user modification to prevent snagging on shorts.
They survive the years well because the leather on them is thicker than most. Avoid ones with any tears, or badly rusted frames, and Proofide plus miles will burmish them like new.
