This miniature steam engine accessory is unknown in country of origin or manufacturer, though the use of U.S. standard screw sizes may suggest an American manufacturer. It is a beautiful example of an antique toy being a miniaturized version of the real thing.
This toy features all-metal construction. The blade is stamped steel. It may have been capable of cutting small pieces of balsa wood. The fence is fixed by two small screws.
The base appears to be made of cast iron. yet it is very detailed and delicate looking. The drive pulley is visible in the upper left. A round belt would have been used to run the saw off of a stationary steam engine.
