Looks like a Yamaha Neo. Probably the easiest tenor horn to find in the U.S.
Sterling / Perantucci 1065HGS Euphonium, 1952 B&H Imperial Eb Tuba, and a bunch of trombones.
Definitely an interesting choice. I have seen numerous orchestras opt for the euphonium if a 'tenorhorn' or equivalent (usually a German rotary-valve baritone) is not available. It certianly makes for an interesting discussion topic as which would be preferred. I would imagine the English-style baritone would be a closer fit to the original tone Mahler envisioned when he composed the work.
