Replacement folding prop - no shaft

I’m looking for a replacement prop for a motor that doesn’t have a shaft.

it was a 2 blade folding prop that was screwed directly to the hub with 4 screws, spacing is ~32mm.
There’s also 4 other screw holes closer together that could be used, they are ~21mm apart.

I’m not sure the brand of motor.
using it for foil assist - open to 3 blade too.

Any insight greatly appreciated.
Thank you!

here is what the original prop looked like
