I found this old prop...

[fc159ou812]

I ran across this old prop recently and I trying to figure out what it is. Its in pretty bad shape, the last laminated board seems to be missing so I having trouble IDing it.

As best I can tell from the bore hole and bolt centers, it fit a Liberty 12 engine.

There are some marking on the prop but I can't quite make them out.

It's in rough shape, but most likely was part of a 4 blade combination that interlocked with a matching 2 blade, used on a Liberty engine and probably for one of the Navy flying boats of the late teens. I doubt that you will find much else about it.

That's interesting... so there is a "mate" for this propeller. I'll see if I can read some of the markings on it. No thoughts about the manufacturer?

I was able to read some of the markings on the prop. There seem to be 2 sets of markings, one on each side of the hub.
