Well, this is interesting! The seller knows nothing about brass instruments, apparently, and can't be sure the horn works! However, looking at it, the horn is complete with no troubling damage. The pistons are shown and MAY be worn, but may also just be tarnished. Normally when pistons are "worn out" they show more random discoloration and pitting. It is finished in satin silver and a molded hard case is shown (very simple design that actually protected my old Besson pretty well). The buy-it-now price is $1,199.99.
