This is likely a National tabletop electric grill released over 50 years ago. The design is good, and I can tell it's made with sturdy materials like iron and plastic. I've only used it twice. It was used, so it works without any problems. Although it's a tabletop grill from over half a century ago, it's a beautiful item that's clean down to the details. I grilled fish, and it cooked perfectly like new. There is no box. There is no instruction manual, but the functions are simple, so you just turn the knob. Dimensions: 40 x 30 x 15 cm
