Look closely.... it is not.
First pic (OP's 'attached images" pic) you can see pinky table, it is the Bundy-style, old-school pinky table. You can also see "Selmer USA"
This is a horn from perhaps the 1970's, maybe early 80's at newest; a Selmer USA Baritone sax. Made in USA. It's a vintage-style horn. As Milandro and Bflat both note. Essentially the same horn as a Bundy, or a late Buescher 400.
"Student" horn ? No-Yes. Depends. By the yardstick of its design and quality of build (and tone), no more a 'student' horn than a 12M is a student horn, really...
Although, yes...most of these back in the day were sold to schools and were typical band-room occupants....
Great bigass tone, good intonation. Blowing response is pretty good. The pinky table is somewhat stiff and clunky, however, not exactly fluid. But no worse than many vintage bighorns in that category.
Market value of a playable one around $1100-1600, depending on physical condition.
