⭕ Rare antique Tin Key-Wind Pontoon Boat Toy. Tin toys like this would be played with in the water and often did not last very long, so I suspect that this Pontoon boat is quite rare. It looks to be German and is dates from the early 20th century, circa 1900. Measuring 9 long by 4 ¾ wide and5 tall this early painted tin toy depicts a man driving a pontoon boat with a seat in the front for passengers. We used a clock key to wind the motor and the propeller began to spin, and actually it spun for quite a while! As you can see, there are some paint flecks to the original painted surface, but there are no other problems or any restorations.
