Alto trombone after Crone

After Johann August Crone, Leipzig 1780

Original: Museum of History and Shipping, Riga

The Crone is a late classical/early romantic alto trombone. Although dated earlier, the Crone trombone is already much further developed than the Schmied in its bore size; at the time, developments among Leipzig instrument makers were considered more progressive.
