1960s Piano Accordion

Can you Identify this 1960s Accordion

I have a vintage 1960′s era piano accordion without any identification marks such as Manufacturer, Model, and Serial Number. I was wondering if you have ever seen this particular accordion before, and if so, can you identify the Manufacturer and Model?

The only information on the accordion itself is “1027″ stamped on the bottom.

If anyone has any information on brand, type and value of this interesting 1960s Piano Accordion, please leave your comments below or send me email at: info@accordionstop.com
