This is what is stamped on the propeller, C707-80, 2000 RPM, HP 225, ATC NO 457, ESIGN, 33502. Other than the information on this website, would anybody know a more precise application of this propeller? Thanks for any helpful information.

Did you see this page (http://www.woodenpropeller.com/MWPHartzell.html)? It's listed there for the Beech 17L and the Cessna T-50 (Bobcat), both using a Jacobs 225 HP radial engine.

This model turns up frequently from a variety of manufacturers. They were produced in large numbers before introduction of a superior performing and durable metal prop, so hundreds and maybe thousands of them quickly became surplus items as the aircraft were retrofitted with the new models.
