I was also collecting this series. It came out of the warehouse. It was in its original box, so I bought it used, but it seems the previous owner probably just kept it stored away. It goes well with the "6107" series, which I am listing at the same time. It has an elegant pattern. According to the backstamp, this is from 1955 or later.
