Default Paragon

Good day forum members;
The wood prop is a Paragon with an 8.8 x 5.90 stamping with 8 inch holes on an 8-inch BC in a 10-inch counterbore. There is a written number 1469 on the hub it is brass tipped and the front area has a squared off recess. Originally had a shellac coating with the paragon decal but now weathered off, no indications it had been mounted. Any help would be welcome. Thank you

It's part of a four-blade combination, most likely for a Liberty engine, and was probably manufactured in the late teens or early twenties. A stamped anchor mark somewhere on the hub usually indicates Naval usage, a cloverleaf Signal Corps (Army) usage.

The hub is cut to interlock with a complementary propeller to make the four-blade. The method was less expensive to manufacture and easier to transport than the unit type construction more common in British props from that era.

Thank you for the prompt and knolageble reply. As a pilot and a IA I was wondering about the nature and purpose of the front end hub design.

And you can tell that yours is the rearward blade in the combination. Somewhere is a matching blade that has the rear of the hub cut to match.
