Beats me, but it isn't for that horn.

Yeah, french horns have things like this. Usually they are used to bring an F horn down to Eb. A lot of brass band music is written for Eb horn, so the F horn player just jams that extra tubing in there and reads the Eb music as if it were for F horn. It is, essentially, a leadpipe extension.

Also, historic brass instruments (such as natural horn or natural trumpet) use different "crooks" to put the instrument into a different key (the instrument doesn't have valves).

I've never seen such for euphonium/baritone/tuba. It doubt it is as effective as the higher pitched trumpets and french horns. Correct me if I am wrong, but an extension in the leadpipe to lower the pitch of the euph/bari/tuba would need to be combined with an extension of all the valve slides. I believe using the extra tubing on this particular instrument would make it an intonation nightmare (if it isn't one already).

Thanks.

Tempting to get it just for the "hard case mouth piece tuner" -- I have a couple of hard case mouth pieces that are badly out of tune ...

Q: Does the horn play? It appears to have all connections with the exception of a valve button. ???
A: Hi, sorry, I really don't know how it play or if it play. Thanks.

Its like the old fight/hockey game joke;

What if you were watching someone play a baritone and a mellophone part broke out?
