the International Rollei Club

Hi there. I found an old Rolleicord in my parents basement. They got no idea what it is, but i figured it might be something valueable, so i didnt throw it out. But i need help in identifying and how i can get it to work ( if it works ) and what its worth. Hope you can help me.

It looks like a Rolleicord 1a (type 3), a model that was made between 1938 and 1947. You may get an idea of value from eBay, but much depends on condition and whether it needs to be serviced.
