propeller ID needed

[junkfinder]

I purchesed this small propeller recently from an estate auction. It is 52'' long and 6'' wide. it has a heavy iron ring in the center of the hub with square head bolts. it is made from a single piece of wood and has no markings. Everything about this propeller apears to be original and extreamly old
Please help

Unlikely to be an aircraft propeller, I'm guessing that it's from some kind of fan. It will be hard to identify, I think.
