This is a very late Hupfeld Atlantic, I believe. Some models were fitted with a Xylophone or Glockenspiel. The Music Museum in Beeskow has one with a Glockenspiel installed. The Arnold Chase collection in the United States has an extremely rare Hupfeld Pepita Model I which appears to be nothing more than an extended Atlantic with Snare Drum, Cymbal, Glockenspiel, and Accordion.
