need help with propeller id

[wirenut01]

I am needing some help IDing a propeller I recently aquired. The only markings I can find on it are: MB598 56742. It is 69" long, and has brass edging on the tips and approx 3/4 of the length of the blades. I can post pictures if needed. Thanks for your help.

Pics might help. I certainly don't recognize the number pattern from anything.

I don't recognize the number either. Someone sure cut up the hub area and drilled extra holes. Maybe to mount a clock or barometer. That's a shame.
