This stunning antique seems perhaps to have been an old salesman’s model, but I cannot verify it. What I can say with certainty, this is an exquisite model of a two-cylinder steam marine engine. Made of brass, with a wooden base with plexi cover. This engine is in perfect condition, and would be one of the premier models you could have in your collection. The engine measures 6” x 5” x 3”, the case 5.5” x 7.25” x 7.5” h., and weighs 3 lbs. 4.6 oz.
