I recently acquired an airplane propeller that is embossed "Pratt & Lambert Finishes" on both sides of the propeller blades.
I know little about airplane propellers, but I did some research on Pratt & Lambert and found out that they sold varnishes used on early airplane propellers. Several Pratt & Lambert employees served in World War I, some of whom were killed or wounded. During this time, Pratt & Lambert, which had a large factory complex here in Buffalo, New York, printed a sales periodical entitled "The Propeller." (Reference http://scwhitegenealogy.com/propeller.html)
I'd like to find out if this propeller was made during World War I. The propeller is 8 feet from blade tip to blade tip. The thickness of the hub is 4 inches. The diameter of the hub is 7 7/8". There are several stamps on the shaft. Please see the accompanying photographs for specific prop data.
Any information on the manufacturer, time-frame, and the likely type of aircraft the propeller was designed to be used on would be greatly appreciated.
Thank you for your time.
Jim.
