Fit is outstanding for a Yamaha YTS-52, the quality of construction is excellent and overall the value is superior.

This case is a great value.

Great value

It is a great value.

This case is of first-rate quality and a very good value for the money -- only problem for me is that it did not fit my 1955 Conn 10M tenor sax

Though, any tenor with a beefy neck brace, as the Zephyr from that era does, the neck doesn't fit quite as well as it could.
