The horn looks to be in decent shape and comes with a hard case. The serial number stamp shown does not have a letter to indicate high or low pitch, so I THINK that means it is an A440 instrument. There are many photos in the lower part of the listing, which show many details. NOTE: as you scroll to a thumbnail, you need to click it and then scroll back up a little to see the expanded view of that one above the thumbnail grid. Took me a minute to figure that out! The starting bid now is $375 and there is no buy-it-now button, so it is hard to predict how high this will go. Might turn out to be a good buy!
