Hi there, my Mom has a Harpeleik Zither, it is about 2 feet by 2 feet. It was origanally from Norway, but has a stcker on the inside that says John Skaug Music shop, 1211 Belmont Ave. Chicago, Illinois. It has been in my family for a very long time, my Mom recently passed away and my Dad is curious about finding more about it. Any information would be appreciated.It is in good shape.
