This is a hard case for a horn made by Alexander. It's from when I purchased a 103, but I'm not sure if other models can be stored in it. I bought it about 10 years ago, but I haven't taken it outside, and I've only occasionally stored the instrument in it at home. The inside is relatively clean, but there are some noticeable stains on the metal parts on the outside, so please check the photos. There's a keyhole, so it probably could be locked, but I've lost the key. It's no longer manufactured, so how about it for those who store their instruments at home or travel by car? I plan to wrap it in bubble wrap for shipping.
