Description This is a right-hand Vair pitch marine propeller, that was made by BCK [Black Clawson-Kennedy] at Owen Sound, Ontario. The pitch is 28 and a half inches, while the diameter is 36 inches. This would make it suitable for a diesel vessel. The propeller is made of manganese bronze.

Provenance Prior to the 1950s take over of the plant by Black Clawson (New York-based), the propeller-manufacturing was done by Wm. Kennedy & Sons Ltd.

The propeller might be dated 1963 - this is an assumption from the "63" numerals on it.
