Vintage Wolverine Tin Litho Wind Up Toy submarine with the key. Heavy Tin construction. Some Rust Spots, see pictures.

Comes with everything pictured. Nice 3 blade propeller, which does spin when wound. 

Missing wheels underneath?  Missing something on the stern deck, I don't know what: maybe a flag? 

Great vintage tin toy. I don't know the year of manufacture... the machine guns that are shown on other boats are litho on this one.

Measures 13-1/2" long and is 4-1/2- 5" tall to top of key.
