Please help me identify this propeller :)

[grnerd]

It measures approximately 104"

The center bore is approximately 3"

The bolt hole circle is approximately 6.5"

There are 8 bolt holes, and one is larger than the other 7

There are no decals or other markings.

I am sorry if I have left any vital info out, please ask me any questions you have.

Thanks in advance for your help!!

Is there anyone who can give me an idea of where to start to research this one?

One problem is that although there seem to be a lot of propellers around with drawing numbers that are prefixed with "H" (at least any with three digit numbers following the H), there don't seem to be any listings of them in the common reference materials. Eventually something will turn up, I hope, but right now they are more of a mystery than anything else.
