I did confuse myself with that CL4.jpg pic. I thought it was of the clarinet, not the mouthpiece. However, that really doesn't change my post. I just have to add a couple comments:
* A mouthpiece can be purchased separately from the horn. It is certainly possible that the same folks who made your clarinet made the mouthpiece, but it's generally a poor idea to say that the clarinet is an X because the mouthpiece has an X stamped on it.
* There were about a billion instrument manufacturers in Germany. Helen, one of our CEs and Germanic sax expert, might have seen that harp stamp someplace (again, that doesn't necessarily prove who manufactured it), but the only manufacturers I can think of that used a stamp like that were French.
Here's the good and bad:
* There are some old Albert System horns out there that are worth a bit (like $1000+). However, you need a correct identification and my clarinet identifying skills aren't that good.
* There is a possibility that your horn uses the High Pitch (HP) intonation standard. High pitch horns can't play with modern instruments and a keyed woodwind cannot be converted from high pitch to the modern low pitch standard, thus they are generally valued extremely low. How can you tell what pitch you have? Well, if the horn is in playable condition, use an electronic tuner to check. Most of the notes are in tune at A=440hz? That's modern pitch. Most of the notes in tune at A=457hz? That's high pitch. There was also a German standard around WWII of A=435hz. That'll just sound a bit out of tune, but you may be able to correct for that if you're a good enough player. Anyhow, if the horn isn't playable, look for an HP or H, LP or L, or A=435 or A=470 stamp.

* I can't tell if you have an A, Bb or C clarinet, just by looking at the pic. In a general sense, A clarinets are generally worth more. An easy way to check, other than with an electronic tuner, is to put the horn next to a modern Bb clarinet. A lot bigger? A clarinet. A noticeable bit, but not incredibly so, smaller? C clarinet.
One thing you can do, especially if nobody else here has seen a horn like yours, is to browse eBay.de -- that's the German eBay 'site -- and start looking for similar horns.
