Description
This item is in great condition. The top flat surface has 5 water-droplet sized spots of copper discoloration (green tint) as well as a thumb-size green discoloration near the serial number. The serial reads F60725. The sides have decorative markings on them, but the front and back have no markings. The lever on the right functions as a reset. The red key moves up and down, but I can't figure out how or if it works (the oldest calculator I ever used was made 80 years after this beast.
