Here is a picture of a very similar sword.  Unfortunately, I cannot provide too many specifics because the book is in Russian about German swords.  However, I can make out that this sword dates circa 1920-30.  Looks like a similar match although the scabbard is different than your example but it has been hypothesized that perhaps it is a refitted scabbard.
