Wooden model of white pine and maple, except for sails and gearing. A flat triangular body rides on three wheels, the single rear wheel turning under the direction of a tiller. A system of gearing controls the single fore-and-aft sail. The model was reconstructed in 1959 from disassembled parts which existed in the collection. At that time a missing gear and idler connecting the two sail frames was fabricated. (Robert P. Multhauf, "Catalogue of Instruments and Models," 1961).
