USS Monitor Ironclad Deck Plating & Beam Construction Drawing (Hand Sketch)

This is a hand-drawn pencil and colored-pencil illustration on lined notebook paper, labeled "USS Monitor Decking & Plating." It is not an automotive document; it depicts the deck construction of the USS Monitor, the Civil War-era ironclad warship. The drawing shows an isometric cutaway view of the ship's deck structure: overlapping riveted iron deck plates (shaded blue/gray with rows of rivet heads) laid over longitudinal wooden deck planking, which in turn rests on heavy transverse wooden beams. Handwritten callouts identify the structural timber dimensions: "10"x10" oak" for what appears to be the deck beams, and "7"x14"" (material partially illegible, possibly pine) for the planking layer. The drawing is signed "Johnston." A reader can learn the general layered construction method of the Monitor's armored deck, iron plating over wood planking over oak beams, and the approximate timber dimensions used. The document contains no automotive content, no fuse or wiring data, no part numbers, and no dates. Despite being filed in a 1988 Ford Bronco gallery on SuperMotors.net, this drawing has no applicability to that vehicle; it appears to be a personal historical/model-building reference sketch, part of a set with related files (deck_plates1a.jpg, turr_beams.jpg).
