Hmm....Which is correct?

Yamaha USA says this:

This product is discontinued and may not be available at all dealer locations.

Model: YSS-62
Years: 1979-1991
Key: Bb
Auxiliary Keys: High F#
Engraving: Yes
Finish: Gold Lacquer
Keys: Gold Lacquer
Finger Buttons: Pearl
Current Model: YSS-475

And the Yamaha catalogue I have says that the YSS-475, which I own, is an intermediate horn.

But, I played a 62 sop yesterday, and it is far better than my 475 - in every sense of the word. Based on the different features (the 62 has single unit base, blue steel springs, engravings, more refined craftmanship, etc.), I think that the 62 is a pro horn, like a lot of posts on the Internet say.

So, is the 62 a pro or intermediate?
