The seller keeps calling it a "trumpet" which is sort of an interesting bit of terminology. What do you think it's pitched in? My eyes agree that it's probably a tenor Bb, but tornisters can be confusing. Very cool horn.

It's a Cerveny tornister baritone.

Which I guess could easily be called a "bass trumpet"; an octave below a Bb trumpet.

Edit
Ok taking taper into account, how about "bass cornet"?
