This model is the DeBoer 80" Seaview model kit. 
 
At one time, this was a fully functional model. It has, however, been completely stripped and is now bare and ready for the installation of a control system of your choice. 
 
The Deboer Seaview is an exceptionally rare model kit and is currently out of production. Original purchase price of the model kit was approximately $1800, so you can see the value of this package.
