This is an exceptionally nice example of the sweet spot MK VI alto, #148xxx.  These are the medium bow altos that are preferred by Sanborn and Kenny Garrett among many others, for their superior intonation, powerful volume and thick upper register.  The hype is real about these and this one particularly is a complete phenomenon.

The condition of this horn is just museum quality original lacquer. original pads and original setup that has barely been played and feels and looks just brand new.  This plays as is on the original pads.

This is an extremely rare find and not an every day horn.  It plays every bit as good as it should and even among 140k altos this is probably the best and most balanced sound and feeling out of all I have played.
