The Conestoga Big Bang Cannon Model 9B Boat Carbide Toy is a vintage military cannon made of cast iron, approximately 100 years old. This unique toy is perfect for both boys and girls who enjoy collecting and playing with antique toys. With its historical significance and durable material, this cannon model offers a glimpse into the past and is sure to be a standout piece in any collection. these carbide cannons are just noise makers not made to fire anything. I tested this boat and it is very loud works well. The turrets and the flag are replacements. I believe everything else on it is original.
