Question about modern propeller

[dally more]

I was given a wooden propeller, 25 laminations, with no accompanying information. It is approximately 6' long 8" wide. 2 1/4" alluminum plug in center, stainless steel cuffs. Hub diameter of 6 3/4". Bolt spacing is 4 3/4". Counter rotating possibly. Partial model number 72CA-5. Serial number 2334. After paint was removed, there was an outline of a decal that looked similar to Maxwell-Banks. Fabric underneath the red tip paint.

Can you post a picture? Banks Maxwell made mostly airboat type propellers, although they did make some for aircraft. If it has squared off flat tips it's most likely the former.

Here are the pics.
Thanks.
