Art Deco Submarine model carved wood metal

Original hand carved model submarine gun-boat. Not a production piece but completely unique and built as "one off"!  The submarine model is a very rare nautical theme, typically you can find a plethora of sail boats, ocean liners and cruisers. This one is particularly detailed with it's landscape base depicting the boats presence on top of the water.  Nice metal details with portholes, deck and viewing areas. A terrific size and would be stunning in someone's model collection. It was purchased in Argentina, but hard to know the exact origin since so many European toy models are found in this country.
