2 prop id's needed

I purchased 2 wooden props at an auction and I'm trying to get an idea for what aircraft they were used on.

On is a Hamilton Aero Mf., Milwaukee, Wis. The numbers as best as I can make out are DESH-773RH, No 18402 and 5134 at the 12 0'clock position above the main shaft

The other has no visible numbers on it.

Both are scimitar shaped and about 7-8 feet long.

If I can figure it out I'll post pictures.[/img]
