Think it's a 1241. Looks like a 22in bell, but hard to tell, might be a 19.

2K W/upright bell and blue velvet.

Looks like pretty nice shape. Amazingly, I can’t see any obvious dents, just lacquer damage. Of course they don’t show the other side. I wish I could see the valves to assess their condition.

Any speculation about the age?

70s? Early 80s? I can't make out a SN. Someone who knows when they changed the curleycue 3rd valve slide would know better.
