Sorry but I know nothing about this item just want is shown in pics. Parsifal Melodeon made in Germany. It spanned two generations so has to be close to 100 years old I would imagine. It does make noise and pulled apart and squeezed. Some of the buttons are missing and shows some age and wear. Would be a great display piece or to restore. Asj questions if you like, be happy to answer what I can. See pics for overall condition.
