Help Identifying Aeromarine Propeller

[jeeplvr247]

Hello all, I am new to the site and the world of airplane propellers. I have stumbled upon an Aeromarine propeller and was wondering if I could get a little more information on it like a year, model of plane it came off, and approximate value. It appears to be in good condition but I am no expert on the matter. Here is some of the information on it:
Part no - 1139
Mfg no - 4
RPM 1800

That's not enough information to identify it.

I have not bought the prop yet but I am considering it. If I get it I will have all of the information but that is all I have for now. How much is a typical Aeromarine propeller worth?
Thanks
