This is a case for an Alexander horn, specifically for a 103 model. I bought it used, and it contained a 103. I'm selling it because I bought a different case and want to organize my things. This case held a 1990s-era 103 and is still usable (I was actually using it until recently), but it shows considerable age. Please examine the photos and understand the condition before purchasing. There's a three-dimensional sticker from the original seller, Shimokura Gakki. I've left it on to avoid any potential damage from removing it. The previous owner seems to have modified it to be carried on the back, but I don't have the backpack straps, so they are not included. There are no keys. It's heavier than modern cases, but it feels sturdy and like it would properly protect the instrument from impacts.
