Thank you for viewing. This item was purchased at an air show more than 10 years ago and has been displayed on a shelf. It's a simple toy that moves forward a little with a spring mechanism when pulled back and released. However, upon closer inspection, it's quite well-made, and I think it would be appreciated by enthusiasts. I'm not entirely sure, but judging by the weight, the surface appears to be die-cast metal, and the underside seems to be plastic. My apologies if I'm mistaken. Please purchase only if you understand that this is a used item. Those who are overly concerned about condition should refrain from purchasing. Approximate dimensions (measured by an amateur): Length: 185mm Wingspan: 130mm Height: 65mm Weight: 146g
