Robert,

It's for a Cessna AT17 "Bobcat".

The drawing number (43K13605) can be found in the Sensenich listings of military props, where it corresponds to a civilian model number of 90JA-81, which then can be found on this page.

The "43" in the drawing number indicates the year of the contract with the military for that model. It was not unusual for propeller manufacturers to build propellers under a license agreement from another manufacturer, in this case probably Sensenich.

The other numbers stamped on yours are all consistent with the correct engine, etc. for that plane.

For some reason, lots of those propellers seem to be around still. Many of them were manufactured by S&S Propellers, Ltd. in Winnipeg.
