Here is a downloadable scan of official drawings of the ship of the line USS Pennsylvania 1837.  The drawing was probably prepared by the Philadelphia Navy Yard under the direction of Samuel Humphries sometime between 1821 and 1837.  This scan shows a plan (overhead) view of the magazine platform.
 
The original scan was obtained from the US National Archives and Records Administration, College Park, Maryland.
