Default help with a neighbors display piece

Greetings, I would appreciate any suggestions identifying a neighbors display
piece. Found in a farm field in Missouri many years ago.

8 foot diameter
8 bolt holes
metal sheath
stamped 4012-4 perpendicular to blade

Apologies for poor quality of photographs.

Curtis R4?

Thanks!

It's too short for an R4 .

Many propellers look the same, but had widely different usages. I don't recognize the number sequence, but there are certainly a lot of possibilities.

You might be able to narrow it down somewhat based on the hub dimensions, but it's unlikely that you'll be able to positively identify it.

That looks a lot more likely.
