Textbook early issue jackboots or Knobelbecher marked Ober Main

Textbook pair of early issue jackboots or Knobelbecher in very good condition. The boots are nicely matching and both marked Ober Main 29 6. Although these jackboots seem to be in unissued condition the leather has dried out over the years and it shows some cracked areas. If you have a mannequin with cut feet it should however not be a problem and it would be a very nice pair!
