Help identifying a propeller

[bcumback]

A propeller is coming up for sale soon and I would like to identify it.
The dimensions are: 10' diameter , eight bolt holes 8" spacing,
3.5" bore, 7" hub thickness, 10.5" hub width. I'm guessing that it came off
a Liberty V-12 (400 HP) because of the hub size. Also it was displayed with
a Cylinder from the Liberty and a picture of a large flying boat. It's hard to tell
from the picture but the flying boat appears to have a pusher engine and this
prop is a tractor. It does have some numbers stamped on one side close to the
hub but, I couldn't make them out without taking it down from the wall. I'll try and send a picture with this thread.
Thanks,

How do you know that it's a tractor?

If you can, find any and all numbers that are stamped on the hub.

Prop rotation

Assuming the Liberty rotates clockwise , this would be a tractor.
I'll try and get any numbers off the hub soon. This prop is about 70 miles
from my home. I have some pictures sent to me by iphone and I can't save them to me computer for some reason.
Thanks for the reply

Adding to my 1/6/12 post

I had a chance for a close up look at the prop described in my post of 1/6/12
and unfortunately I think this propeller was refinished although it has been at
least 43 years ago. The only marks I can find are N-97B7 on the first line
_ _ _ RH on the second line , I cannot read anything from line 4 and on line
5 it shows _ _ L
The dashes indicate were a letter or number was but is unreadable probably because of the refinishing.
I don't know if this is enough info to help identify this prop or not.
Thanks for looking

A picture might help. There are hundreds of possibilities based on the information you've given.

Picture emailed to me:



It does look like a fairly typical Liberty engine propeller which could have been used on any number of flying boats or land planes such as the DH4. I agree that it certainly looks refinished, which would help explain the difficulty in reading the identification stampings.

Here are several others:

Unknown Liberty engine prop

Without legible stampings and a credible reference to those numbers, all you can say about a prop like this is that it was "likely" to be used as described.
