I think the drawing number indicates that it was made by S&S Ltd. of Winnipeg, Canada. The Hamilton decals were likely added by someone after refinishing it.

I don't recall what aircraft that went on, but it's a fairly common model of display propeller. I'll see if I can dig up information about that model, unless someone else has it right at hand.

Will you give us the diameter (length)?

Identifying MAY 1943 Prop

S&S made a number of different props but yours might very well be for a PT-26. You will see some ingredients echoed in your data stamps on the prop hub in this text copied from a page found during a web search:

The Model 6-440 Ranger engine was the last and largest of four 6-cylinder engines produced by the Ranger Engine Division of Fairchild Aircraft. Designated by the U.S. military as the L-440, this engine was used almost exclusively by Fairchild aircraft. This was an inverted, in-line, 6-cylinder engine.

Fairchild Aircraft designed and built a series of wood and fabric training airplanes for the US Army Air Corps, Canada, Norway, Brazil, Ecuador and Chile. [Thanks to history furnished on a web site by Kevin Murphy]. In the US, the designator "PT" for "Primary Trainer" was used; in other countries these airplanes were called "Cornells". Kevin's notes continue:

The final version of the PT-19 series, an enclosed-cockpit version designated the PT-26, was designed for the Royal Canadian Air Force in 1942 with a canopy over the two cockpits. 670 of the PT-26s were provided to the RCAF through Lend-Lease and, in a variation on the Lend-Lease theme, the U.S. Army Air Force ordered 1,057 PT-26s from the Canadian manufacturer, Fleet Aircraft, Ltd. All PT-26s were equipped with the 200 hp Ranger engine.

A total of 7,742 Cornells were manufactured for the AAF, 4,889 of them PT-19s.
