Default ID help, please!

I would appreciate any help that could be provided in identifying my propeller, so thank you, in advance. It has 12 holes, so I assume it has be re-drilled to fit a different engine.

Stats:
91.750" Long
2.700" Inner Diameter
5.250" Bolt Hole Circle (12X) 0.460" holes

Here are the links to my pictures:

Characters in this picture are: [ DES H-609 RH, NO 13117 ]

Characters in this picture are:[ (clockwise) 5052?, 3, 1, 4 ]

Characters in this picture are:[ PATENT NO 1.404.808., JANUARY 31TH.1922]

This is an overall view of the prop:

Default Nothing???!!!

Oh, come on, guys!! This post has been up here a week, been read a few dozen times, and not received a comment??

I assume that means that this is a difficult nut to crack- the likes have never been seen before? Or does it mean that this prop is so common that every TGIFriday's has one over the bar?

Humbly,

Brian.

It's the former. I've looked through some stuff and haven't been able to match the number. I'll spend a little more time at it as soon as I get done with my daughter's wedding this weekend.

I too have looked through some stuff and tried to do research on this prop to no avail. However, I'm not finished yet!

I looked up the patent number stamped into the metal sheathing. It was issued on the date shown on the prop to one Harold M. Gusdorf of Indianapolis, IN for "... new and useful Improvments to Two-Ply Pigskin Belts..." relating "... to the structure of belts for pulleys ...". See http://patimg1.uspto.gov/.piw?Docid=...iew+first+page for the full text and drawings. Nowhere did I see any mention of aircraft, aviation or propellers! What a mystery!

You may need a special browser plugin to view the patent office images. They recommend http://www.alternatiff.com/ which I installed with excellent results.

Default Adding to the mystery...

Lamar-

Thanks for your hard work. It looks like you are coming at this from several different angles.

I see what you mean! This is odd! The date and the patent # match, but, on the surface, it certainly doesn't look related to my prop!! Is it normal to have a patent # on a propeller?

I have looked through the pictures of other props and although there are some similarities, it does look a little different than any of the others. In your searches, have you seen one that looks like this one?

Brian

No, I'd say that's prettty unusual unless there's something unique about the prop.

I don't see anything unique or really unusual about this one.

I've now exhausted all my resources and come up with nothing else new. Sorry.
