Bundy Baritone
Saxophone Neck

For Sale

The Outside Diameter of the tenon is about 21.8 mm or about 0.86 inches. Tenon length is about 19.6 mm.
Looking at the first group of photos below you can estimate whether the linkage of the neck octave key would mate with the octave mechanism on the body of the sax.
By looking at the photos, you may be able to get some idea of where the linkage has to be, relative to the receiver.

The factory did not do an especially good job putting the cork on this neck.

I just happen to have a Conn 12M bari on my workbench.
By way of comparison this Bundy neck tenon is quite a bit too small for the Conn.
The Conn 12M (s/n C840xx) neck tenon has O.D. of about 24.7 mm, I.D. of 22.2 and a tenon length of 21.4

But the second group of photos show that this Bundy Bari neck would be a good replacement for a Selmer USA Bari Sax.
The Selmer Bari Sax is serial number 1206xxx.
The Selmer USA Bari has bell keys on the back of the bell and a Buescher-style lefthand pinkie cluster.
Neck tenon size is a good fit, both at around 21.8 or 21.9 mm O.D. and 19.6 mm length.
The octave key mates with the octave mechanism and the octave vent is in the same position.

June 2011 - This Bundy neck is also a good replacement for a Selmer Signet Low A Bari (875xxx) sax.

I am getting some feedback that this neck may work on a Buescher "400" bari. But I haven't corroborated with first hand experience.
