This is a "studio model," from the Delande company archives, the main purpose of which would have been to serve as a model from which dies would have been made using a reducing machine.  Only a very limited number of studio models would have been made with just a few being sold, disseminated or used for special purposes.  In some cases, only one "master" studio model would have been created with the artist or manufacturer choosing not to retain or disperse other examples, using it purely in the process of die-making.
