Gebruder Bing Nurnberg Bavaria Germany Toy Tin Boat

Excellent find at a thrift store recently. For a mere $6 I left with this nice piece. Made by Bing toys in Germany this sail boat (I believe it may be a yacht of some kind). With a burgundy, light green, and light blue coloring. Key wind-up but unfortunately I don’t have the key. It also seem to be friction operated as well. The insides are in really good condition. Some paint chipping, along with other signs of aging. It measures 9” long by 7” wide. The sail has the GBN Bavaria logo.
I can’t really seem to find another one identical to this one. A really nice find!
