Here is a downloadable scan of an official builder's drawing of the Netherlands' Heiligerlee-class monitor Cerberus.  This plan was probably prepared by the ship's builder, Nederlandsche Stoombootmaatschappij in Feyenoord, Rotterdam, circa 1867.  This scan shows the inboard profile view and plan (overhead) view of the main deck.
 
The original scan was obtained from the US National Archives and Records Administration, College Park, Maryland.
