This is a DEG model 1220. It was marketed in the catalog as a "marching alto/French horn", but it is really an alto cornet in F (just as it appears). Made by Willson as mentioned, who also sold an Eb version in their Swiss home market. Most of them have the small 6" bell that this one has, but there were also 2 bigger bell sizes that I know of. None of them show up very often for sale, but when they do they are always listed as a mellophone.
I had a 1220 for a long time. They are really fun to play - free-blowing, pretty good intonation, no weird quirks, works best with an alto horn mouthpiece. The sound on its own isn't the most interesting but certainly pleasant, and does indeed sound like a big, lower cornet (at least with the small bell). It is actually not much bigger physically than a normal cornet either, making it a great travel or desk instrument to noodle around on.
I got a ton of use out of mine in recording sessions, if you can believe it. Its sound blends with pretty much anything, especially trombones or flugelhorns. So when writing for bigger horn sections that I would record, I would often score it in between the flugelhorn(s) and trombones and have it play with both. A good circular mellophone like the Yamaha YMP-201 (non-M) also does this job well, but the DEG 1220 is more convenient with its very small size and front-facing bell. I never had a case for mine, but it was nickel plated and built like a tank so it never got so much as a dent getting thrown around without a case. They were designed for marching band use, after all.
That's a good price for the one posted. I wouldn't mind owning one again...

Night and day! The frumpet is truly awful in every way. I own one of those too, and it is horrendous. The 1220 is an actual musical instrument.
I mostly play the slidey thing.
