Here are some larger images of the Vancouver, British Columbia, Canada, Scratch-built Tin "Disney" Nautilus. 
The model is approx. 20 inches in length and is remarkably accurate. The rowboat/lifeboat on the rear deck is present, as well as hatches, ships wheel in the wheelhouse, and closed iris in the side viewing port. 

The model was not for sale as it was in the private collection of the store owner.
