Hartzell 797

[rdwater]

I've recently acquired a Hartzell prop that I hope someone can help identify. Here is the information I have. I hope that you can associate it with a particular airplane for me or give me some insight where to look further.

Thanks, Bob

Stamped on front of blades by hub:
Hartzell, PIQUA, OHIO

That's going to be a hard one to identify. It's not on this list, and I have several other documents that Hartzell sent me years ago, and it's not on any of those either.

At least you have the engine, which narrows it down to some extent.
