Comments: This propeller was manufactured around WW1 for use on the Breese Penquin. Very little is known about the manufacturer, but stampings are essentially identical to this propeller, built by Lang. The aircraft was a non-flying device used for ground training. Some were equipped with roll bars.
It likely was never mounted and may not even have completed the manufacturing process. The tips are a different color but are uncovered with canvas, unlike the Lang. There is some water damage to one tip as shown, along with a small dent in one trailing edge. The decal and finish are original, however.
