Yes, that's the correct original neck and it looks to be in fine condition. I can tell by the mouthpiece print on the cork that it plays just as flat as mine which is simply typical. Don't cut your neck shorter whatever you do. I would concentrate on the original neck. Is the horn and neck clean on the inside? If you want something different from it you'll probably have to look at mouthpiece changes rather than neck changes.
BTW, does it fit good and tight in the sax? That can make a huge difference if its loose.
I think its a Model 162 because it still has the pearl front F and round pearl alt F# along with the early-style Eb/low C keys and other features of the 162 Omega even though it has the oval pearl high F# instead of the Omega flat bar. It is a transitional model to the AS100 but almost every sax they made was a transitional because of ongoing revisions through the whole run.
The neck is a tight fit and neck and body are clean. I have a PhilTone Meyer and John Thomas .080. I dig the Meyer with it a bit more. I know it's subjective, but what pieces have you found favorable to yours?
Overall, I'm trying to talk myself out of trying some Yani's. I don't need a new horn (alto / tenor) at all. I don't. My horns are more than I need.

This is my horn. There are many like it, but this one is mine.
My horn is my best friend. It is my life. I must master it as I must master my life.
My horn, without me, is useless. Without my horn, I am useless. I must play my horn true. I must play more precise than I did yesterday. I must shed so I don't suck.
I will...
My horn and myself know that what counts in music is not the number of notes we play, the squeak of our reeds, nor the faces we make. We know that it is the melody and groove that count.
Not...
My horn is human, even as I, because it is my life. Thus, I will learn it as a brother. I will learn its weaknesses, its strength, its parts, and its idiosyncrasies. I will ever guard it against the ravages of weather and damage as I will ever guard my legs, my arms, my eyes and my heart against damage. I will keep my horn clean and ready. We will become part of each other.
GAS...
Before God, I swear this creed. My horn and myself are the purveyors of my music. We are the masters of our flow. We are the saviors of my life.
So be it, until my playing is pure and there is no waste!
Until I throw the damn thing against the wall because I can't play in tune or find a decent reed.. AND I CAN BUY A NEW HORN!!! WOOOO!
