My wife's great aunt recently passed. We were cleaning out her barn and found a Sensenich wooden propeller serial number P1847. I think that dates it to 1947. It has a large crack (2'-3') down one side. Do I glue and clamp it or let it be?
Thank you
Brian

Let it be. It will NEVER be airworthy, so it's best to leave it as it is, a display propeller only.

Thank you. Is there any way to know what plane it came off of?

There should be a drawing (design number) stamped on it - typically two digits representing it's length, letters denoting the hub, and two more digits representing its pitch. That will lead you to the type of engine and often a list of aircraft models. Finding an actual airplane that it was used on would involve an improbably lucky find of a logbook that noted the serial number.

My wife's great aunt was one of the first women to fly over the Rockies.
According to her, she recovered the propeller from a crash at Windham airport in CT, which is where she kept her plane.
I found a record of a crash in 1946. Wonder if that was the plane
it came from

Extremely unlikely, unless you've got a metal propeller, which typically bends but doesn't "crack".

Did you find any design number stamped on it?

This is a laminated wooden propeller with metal on the edges.
Here's a couple photos of the markings

Markings : MODEL 76RM-44

From this list: http://www.modernwoodenpropellers.com/sensenich.htm it is from a Piper PA-12, J5C fitted with a Lycoming O 235 C/100 engine.
