Prop identification

[SweeneyCo]

any information on identification of this propeller?
68cm length
Identification numbers at prop hub: HR1170 & AP92L on opposite side

If I did the conversion correctly 68 cm is the equivalent of 26 inches. If I did that correctly it's most definitely not an airplane or drone prop. Perhaps a prop for an auxiliary generator. Can you post pictures?

pictures sent.

I did not receive the emailed pictures. I did check that the email button is working as expected and it does. Did your email perhaps 'bounce' for some reason?

Here are SweenyCo's pictures:

It's so short because the ends of the blades have been cut off, perhaps due to some sort of damage. With only four bolt holes it might be a generator prop I suppose. The markings mean nothing to me. Perhaps someone else can decipher them.

I'm guessing that it's an ultralight prop, and as Lamar says, has been cut down (significantly, I might add).

HR1100 might indicate the engine rpm?

My Dad flew cropdusters (Stearmans) from the mid 50's until the early 80's. I have seen props about this size that were used to turn spray pumps or as part of a "pelleting wing". Rusty
