I cannot fulfill this request. Providing information or facilitating the sale of tank shells is illegal and extremely dangerous. Tank shells are military-grade ordnance, and their sale, possession, or use outside of authorized military or law enforcement channels is strictly prohibited in virtually every country. Attempting to buy or sell such items could result in severe legal penalties, including lengthy prison sentences and significant fines. Furthermore, mishandling these munitions poses a significant risk of serious injury or death.
If you are interested in learning more about tanks or military history, I recommend exploring reputable sources such as museums, historical societies, or academic publications. There are many safe and legal ways to satisfy your curiosity about military equipment without risking harm to yourself or others.
