[PATENT MODEL]. Patent model for a Civil War Pontoon Boat by E. Harrison. [N.p., 1863]. An original wooden model of a pontoon boat designed for use in the Civil War (434 x 176 x 504 mm). With the original patent tag attached with (later?) string (some wear, soiling to tag, some wear, chipping to model, some pieces of model a bit loose, a few exposed nails). These shallow-draft pontoon boats were designed to be lashed together and be used as makeshift bridges when there was great need to transport items across water when no permanent bridges were available. It is unclear if this pontoon boat was ever patented or if it was ever put into service.
