Hello, I have this calculator in black. Years ago, the batteries were hard to locate so I stashed it away. This was about 40 years ago. I was so happy to see it on Future Forms. I love this site! Not sure yet if I am going to keep it or sell it but it really is a nice-looking calculator! Anyone have an idea on the value? USD, please. Thanks, Heather Q
